A series of CuII coordination polymers with different topologies, namely [CuL(L1)] • 2H2O(1), [CuL1.5(L2)] • 3H2O(2), [CuL(L3)] • 3H2O (3) and [Cu2L2.5(L4)(H2O)] • 10H2O(4) [ L = 1,1’-(1,4-butanediyl)bis(imidazole), H2L1 = fumaric acid, H2L2 =1 ,1’-ferrocenedicarboxylic acid, H2L3 = succinic acid, and H4L4 = pyromellitic acid], are presented. Different polymeric frameworks are obtained by varying the polycarboxylate anions. These include the threefold interpenetrated diamond structure of 1, the rare twofold interpenetrated 4664 network of 2, and two planar four-connected networks of 3 and 4, which display an unusual Archimedean-type (658) (6482) net containing two different types of nodes and a (5648) (526282)2 (68410) (5462) net containing four different types of nodes, respectively. Thermogravimetric analysis (TGA) curves of 1, 2, 3, and 4 exhibit three similar weight-loss stages.

The reactions of sodium nitroprusside [Na2Fe(CN)5NO • 2H2O] with organotin have been studied. Six new organotin-cyanometalate compounds, [Ph3Sn]2[Fe(CN)5NO] (1), [Bz3Sn]2[Fe(CN)5NO](Bz=C6H5- CH2-) ( 2), [Bz2Sn] [Fe(CN)5NO] (3), [(Bz3Sn)2CN]2 [Fe(CN)5NO] (4), [Bz2SnOSn(MeO)Bz2]2 [Fe(CN)5-NO] • 3CH2Cl2 (5), and [Bz2SnOSn(EtO)Bz2]2 [Fe(CN)5NO] • 3CH2Cl2 (6), have been isolated in these reactions and characterized by the X-ray diffraction method. Each of compounds 1,2,3,and 4shows a 2D polymeric structure containing planar four-connected [Fe(CN)5NO]2- anions. Compound 4 is the first organotin-cyanometalatecompound containing a superlong-CN-R3Sn-CN-SnR3-NC-spacer. Compounds 5 and 6 are the first examples of organotin-cyanometalate compounds of organooxotin clusters, in which the organooxotin clusters are bridged by cyanometalate anions to generate a novel 1D polymeric chain structure.

Two new CuII coordination polymers, namely [Cu2(BDC)2(L)4 (H2O)2]•14H2O(1) and [Cu1.5(BTC)(L)1.5(H2O)0.5] • 2H2O( 2), where L = 1,1’-(1,4-butanediyl)bis(imidazole), BDC = 1,4- benzenedicarboxylate, and BTC = 1,3,5-benzenetricarboxylate, have been synthesized at room temperature. Complex 1 exhibits an unusual, square-planar, four-connected 2D 264 net, which has been predicated by Wells. Interestingly, three types of water clusters, namely (H2O)6,( H2O)8, and (H2O)10, are observed in the hydrogen-bonded layers constructed by the BDC ligands and water molecules. The BTC anion in compound 2 is coordinated to the CuII cation as tetradentate ligand to form a (66)2(426484)2(64810) net containing three kinds of nonequivalent points. Thermogravimetric analyses (TGA) and IR spectra for 1 and 2 are also discussed in detail.

By surfactant-assisted methods, nanoscale Co(O3PC6H5) •H2O species of different morphologies, namely, nanoparticles and nanorods, have been successfully synthesized and characterized. Upon removal of the organic part of the compound, peculiar Co2P2O7 porous nanorods formed.

In this paper, four novel silver(I) sulfonate coordination polymers containing neutral ligands, namely, [Ag2L1(biim)2] • 2H2O( 1), AgL2(biim) (2), [Ag(HL3)(Pic)2] • H2O( 3), and [Ag3(L3)(HL3)(4,4’-bipy)3(H2O)2] • 4H2O( 4), have been synthesized [L1 = 3-carboxy-4-hydroxybenzenesulfonate, L2 = p-aminobenzenesulfonate, H2L3 ) p-hydroxybenzenesulfonic acid, biim ) 1,1’-(1,4-butanediyl)-bis(imidazole),Pic =β-picoline,4,4‘-bipy = 4,4’-bipyridine].For compounds1 and 2, Ag(I) cationsare bridged by biim ligands to form a one-dimensional (1D) “zigzag” chain, and L1 and L2 sulfonate ligands are not coordinated to the silver cation. Compound 3 has a dimeric structure in which two silver cations are bridged by two HL3 ligands. For compound 4, L3 ligand coordinates to a silver cation as a monodentate ligand, and Ag(I) cations are bridged by 4,4’-bipy ligands to form a 1D chain. Compound 1 contains water dimers, while compound 4 contains water trimers. Compounds 1-3 display room-temperature photoluminescence.
