The reactions of AgNO3 with Na2L and Mg(HL)2 (H2L =5-sulfosalicylic acid) gave two luminescent coordination polymers: Ag2L(H2O) (1) and [Ag2(HL)2(H2O)3]H2O(2), respectively. 1 crystallizes in the monoclinic space group P2/n, with a = 7.489(2), b = 16.237(3), c = 8.222(2) Å , β= 92.90(3)°, V = 998.5(3) Å3, Z = 4. Compound 1 is the first silver carboxylate-sulfonate with an extended three-dimensional structure, a framework composed of four kinds of crystallographically unique silver atoms and organic species with three different functional groups, carboxylic, hydroxyl, and sulfonic, each coordinated to the silver atoms. 2 crystallizes in the triclinic space group Pī, with a = 8.307(2), b = 11.246(2), c = 12.590(3) Å, α = 112.68(3), β = 97.66(3), γ = 95.51(3)°, V = 1061.6(4) Å3, Z = 2. In 2, silver ions are bridged by sulfonate groups to form one-dimensional chains, and each chain is connected to the two neighboring chains through the coordination of the carbonyl oxygen atoms to the silver ions of the neighboring polymeric chain to form a two-dimensional network. The luminescent properties of the two compounds are also discussed.

A novel coordination polymer {[Cu(L1)(L2)(H2O)] •5H2O}n (1), where L1 = 1,1’-(1,4-butanediyl) bis (imidazole) and L2 = m-phthalate anion has been obtained by using an unusual crystallization process. It crystallizes in the orthorhombic space group Pna21, which belongs to the crystal class mm2, with a = 9.0521(18), b = 15.401(3), and c = 17.141(3) Å, α = β = γ= 90°, V = 2389.7(8) Å3, and Z = 4. The complex 1 composing a porous supramolecular architecture displays unprecedented four-connected topologyof an 86 net in coordination polymer chemistry. Thermal gravimetric analysis (TGA) and X-ray powder diffraction (XRPD) patterns for 1 are discussed in detail.

Hydrolysis of dibenzyltin dichloride in ethanol has been found to give an unprecedented carbonate anion (CO3 2-)-bridged double-ladder organo oxotin cluster, [(R2SnO)3(R2SnOH)2- (CO3)]2 (1,R = C6H5CH2), with five tin atoms in each ladder. With the aim of obtaining organooxotin clusters with large cavities suitable for host-guest chemistry, we used 1,1’-ferrocenedicar- boxylic acid (H2La) and hexanedioic acid (H2Lb) to replace the carbonate anions (CO3 2-), and thereby clusters [(R2SnO)3(R2SnOH)2La]2 (2) and [(R2SnO)3(R2SnOH)2Lb]2 (3) were ob tained. When 1 was treated with benzo ic acid (HLc) in different stoichiometric ratios (1:4, 1:10), ladder cluster (R2SnO)3(R2SnOH)2(Lc)2 (4) and drum cluster [RSn(O)Lc]6 (5) were obtained. Through the hydrolysis of Cy2SnCl2 (Cy = C6H11) and (C6H5CH2)2SnCl2, two interesting ethanolate-modified clusters [Cy2(C2H5O)SnOSn(C2H5O) Cy2]2 (6) and [(R2SnO)3 (R2SnOH) (R2SnOC2H5)(CO3)]2 (7) were ob tained. All the tin atoms in these ladder clusters are five-coordinate surrounded by two alkyl groups and three O atoms, and have distorted trigonal bipyramidal coordination environments with two carbon atoms and one O atom in the equatorial positions and two O atoms in the axial positions. The structures of all these compounds have been established by single-crystal X- ray diffraction analyses.

Using lowtemperature hydrothermal methods, nanoscale lanthanide phenylphosphonates species with different morphologies, namely, nanoparticles and nanorods, have been systematically synthesized. The possible growth mechanism of these nanorods was discussed. Xraydiffraction,　transmissionelectronmicroscopy, electrondiffraction, and photoluminescence spectra were used to characterize these materials. The photoluminescent properties of Eu(O3PC6H5) (HO3PC6H5) and La0.91Eu0.09(O3PC6H5) (HO3PC6H5) nanorods were discussed.

This article represents a systematical examination of the structures of silver(I) sulfonates incorporating neutral ligands. To survey the influence of the properties of neutral ligands on the structures of silver(I) sulfonates, three kinds of sulfonate anions (L1= 1-naphthalenesulfonate, L2 =p-toluenesulfonate,and L3 = 1, 3, 6, 8-pyrenetetrasulfonate) and three kinds of neutral ligands (pyrazine, Pyr, a divergent bidentate ligand; hexamethylenetetramine, hmt, a divergent tetradentate ligand; and β-picoline, Pic, a monodentate ligand) were selected for study, and five novel silver (I) sulfonates containing neutral ligands have been synthesized: [Ag(L1)- (Pyr)] •H2O(1), Ag(L2)(Pyr) (2), Ag4 (L3) (Pyr)4 (H2O)2 (3), [Ag(L1)(hmt)] •H2O(4), and Ag(L1)(Pic)2 (5). The crystal structures have been determined by single-crystal X-ray diffraction,and these compounds show a variety of structures with different dimensionalities. Moreover, the luminescent properties of compounds 2, 4, and 5 are also discussed.
