Three isomorphous compounds M(CHOO)3[NH2(CH3)2] (M) Mn(1•Mn), Co(2•Co), Ni(3•Ni)) have been synthesized in solvothermal conditions. Single-crystal X-ray diffraction shows that they are all crystallized in the trigonal space group R 3hc with small differences in the lattice parameters. Bridged by the three-atom single-bridge CHOO-, M ions form a three-dimensional distorted perovskite-like structure with dimethylamine (DMA) cations located in the cages of the network. Based on the magnetic data, these three 3D compounds are weak ferromagnets with the critical temperature Tc) 8.5 K (1•Mn), 14.9 K (2•Co), and 35.6 K (3•Ni), and for 2•Co and 3•Ni, spin reorientation might take place at 13.1 and 14.3 K, respectively. At 1.8 K, hysteresis loops can be observed for all three compounds with the coercivity field ca. 90 Oe (1•Mn), 920 Oe (2•Co), and 320 Oe (3•Ni). The canting angles are estimated to be 0.08º 0.5º, and 0.6º for 1•Mn, 2•Co, and 3•Ni, respectively. The magnetic coupling between MnII ions in 1•Mn was estimated based on the model developed by Rushbrook and Wood for a Heisenberg antiferromagnet on a simple cubic lattice and the best fit gives J)-0.23cm-1. At the same time, according to molecular field theory of antiferromagnetism, the J values for compounds 1•Mn, 2•Co, and 3•Ni were estimated to be -0.32cm-1, -2.3cm-1, and -4.85cm-1, respectively. The spin cant in these compounds may originate from the noncentrosymmetric character of the three-atom single-bridge CHOO-. Furthermore, amorphous materials 4•Mn238, 5•Mn450, 6•Co320, and 7•Ni300 were prepared from precursors 1-3 under an argon atmosphere at different temperatures according to the thermogravimetric analyses. As an interesting result, 5•Mn450 was confirmed to be an amorphous form of Mn3O4 with a considerably large coercivity field HC) 4.1 kOe at 30 K compared to that value (250 Oe) for bulk Mn3O4.

Much attention is currently being devoted to the design and synthesis of molecular magnetic materials exhibiting spontaneous magnetization. The main synthetic strategy is virtually to use and connect two paramagnetic building blocks (bricks) to generate polynuclear or extended arrays. Extended arrays of high dimensionalities may exhibit higher ordering temperatures due to the increased number of interacting neighbors. A representative example is the cyano-bridged three-dimensional (3D) Prussian blue-type complexes constructed from hexacyanometalate(Ⅲ) and simple transition metal building blocks.1 One of these materials exhibits long-range magnetic ordering at Tc as high as 372 K.1c Thus far, a number of Prussian blue analogues of different dimensionalities have been synthesized and characterized structurally and magnetically. 2,3 These studies have shown that the lowdimensional materials have Tc values generally lower than that of the corresponding 3D analogues, and the few hybrid 3D arrays.

【期刊论文】FormatesThe Analogue of Azide: Structural and Magnetic Properties of M(HCOO)2(4,4'-bpy)

Reaction of transition metal formate M(HCOO)2•2H2O (M=Mn, Co, Ni) with 4,4'-bpy (4,4-bipyridine) has led to four new compounds with the formula M(HCOO)2(4,4'-bpy)•nH2O (M=Mn, Co (1•Mn, 2•Co), n=0; M=Co, Ni (3•Co, 4•Ni), n=5). Compounds 1•Mn and 2•Co are isomorphous and crystallized in the tetragonal crystal system with the chiral space group P41212. They are of three-dimensional diamondoid structure connected by anti-anti formate with 4,4'-bpy in the cavities of the framework reinforcing the intermetallic connections; the diamondlike net was observed also in their azide analogue (Mn(N3)2(4,4'-bpy)). Compounds 3•Co and 4•Ni are isomorphous also but crystallized in the monoclinic crystal system with the space group Cc. Both structures are uninterpenetrated 3D "CdSO4" type with big channels, constructed by anti-anti formate and 4,4'-bpy. This type of net was not observed in their azide analogue. Residing in the channels, water molecules form a new type of 1D tape constructed by vertex-sharing cyclic pentamers. Magnetic measurements were performed on all of these four compounds. 1•Mn and 2•Co are weak ferromagnets with the critical temperature Tc=5.3 and 7.4K, respectively. 3•Co is an antiferromagnet with Nevel temperature TN=3.0K, and 4•Ni is a weak ferromagnet below 20K. Hysteresis loop can be observed for 2•Co and 4•Ni at 1.8K. As an analogue of azide, formate can be used to construct molecular architectures, which structurally and magnetically have great similarities to and also differences from those of azide. This offers a promising method for the design of new molecular architectures with formate.

Three coordination polymers of Co(II) with dicyanamide (dca) were obtained by adding coligands of 2,5-dimethylpyrazine-dioxide (2,5-dmpdo), 2,3,5-trimethylpyrazine-dioxide (2,3,5-tmpdo), or 2,3,5,6-tetramethylpyrazinedioxide (2,3,5,6-tmpdo) to the binary system of Co-dca. Co2(dca)4(2,5-dmpdo)2 (1) crystallizes in the triclinic space group P1h with a=7.4962(2), b=9.0364(2), c=10.4783(4) Å, R=72.567(1), a=72.557(1), ç=68.814(2)º, V=616.61(3) Å3, Z=1, and R1=0.0345. [Co3(dca)6(H2O)4]•2(2,3,5-tmpdo) (2) is in the monoclinic space group C2/c with a=29.477(1), b=7.3735(2), c=17.4631(7) Å, a=93.652(1)º, V=3787.9(2) Å3, Z=4, and R1) 0.0532. [Co(dca)2(H2O)2]•2(2,3,5,6-tmpdo) (3) is in the monoclinic space group P21/c with a=9.4739(3), b=11.3876(3), c=12.1778(3) Å, •=98.967(1)º, V=1297.74(6) Å3, Z=4, and R1=0.0481. 1 contains an unusual (4, 4) Co-dca layer, representing a rare example of metal-dca coordination polymers with mixing 1,3-í2-and 1,5-í2-dca bridges. The Co-dca (4, 4) layers are connected by 2,5-dmpdo to give an R-Po-type network, which displays antiferromagnetic ordering below 10.8K. 2 is a unique 3D framework composed of 2D twinned 1,5-í2-dca bridged layers, which are connected by Co-H2O-Co linkages. The noncoordinated 2,3,5-tmpdo units and the coordination water molecules form hydrogen-bonded chains that thread the framework. 3 has alternating stacks of usual Co-dca (4, 4) layers through 1,5-í2-dca bridges and organic layers of noncoordinated 2,3,5,6-tmpdo. Weak antiferromagnetic and weak ferromagnetic coupling was observed in 2 and 3, respectively.

Six heterometallic compounds based on the building block [Cr(bpy)(CN)4]-(bpy)2, 2-bipyridine) with secondary and/or tertiary coligands as modulators, {Mn(H2O)2[Cr(bpy)(CN)4]2}n (1), {Mn(bpy)(H2O)[Cr(bpy)(CN)4]2•H2O}n (2), [Mn(bpy)2][Cr(bpy)(CN)4]2•5H2O (3), {[Mn(dca)(bpy)(H2O)][Cr(bpy)(CN)4]•H2O}n (4) (dca) N(CN)2-), {Mn(N3)-(CH3OH)[Cr(bpy)(CN)4]•2H2O}n (5), and {Mn(bpy)(N3)(H2O)[Cr(bpy)(CN)4]•H2O}2 (6), have been prepared and characterized structurally and magnetically. X-ray crystallography reveals that the compounds 1, 2, 4, and 5 consist of one-dimensional (1D) chains with different structures: a 4,2-ribbon-like chain, a branched zigzag chain, a 2,2-CC zigzag chain, and a 3,3-ladder-like chain, 1b respectively. It also reveals that compound 3 has a trinuclear [MnCr2] struture, and compound 6 has a tetranuclear [Mn2Cr2] square structure. Magnetic studies show antiferromagnetic interaction between CrIII and MnII ions in all compounds. All of the chain compounds exhibit metamagnetic behaviors with different critical temperatures (Tc) and critical fields (Hc; at 1.8K): 3.2K and 3.0 kOe for 1; 2.3K and 4.0 kOe for 2; 2.1 K and 1.0 kOe for 4; and 4.7K and 5.0 kOe for 5, respectively. The noncentrosymmetric compound 2 is also a weak ferromagnet at low temperature because of spin canting. The magnetic analyses reveal Cr-Mn intermetallic magnetic exchange constants, J, of -4.7 to -9.4cm-1 (H) -JSCr•SMn). It is observed that the antiferromagnetic interaction through the Mn-N-C-Cr bridge increases as the Mn-N-C angle (õ) decreases to the range of 155-180º, obeying an empirical relationship: J) -40+0.2õ. This result suggests that the best overlap between t2g (high-spin MnII) and t2g (low-spin CrⅢ) occurs at an angle of~155º.
