Hydrothermal reactions between a new flexible multicarboxylate ligand of 3-(2-carboxy-phenoxy)-benzoic acid(H2L) and transitional metal cations of M2+(M = Cu2+,Ni2+) in the presence of the secondary ligands of 1,10-phenanthroline(phen),2,2'-bipyridine(2,2?-bpy),and 4,4'-bipyridine(4,4'-bpy) afford two novel coordination polymers Ni2(H2O)2L2(phen)(μ-4,4'-bpy)(1) and CuIIL(2,2'-bpy)(2).Both compounds were characterized by X-ray crystallography.Crystal data of 1:C31H24N3NiO7,Mr = 609.24,monoclinic,space group P21/c,a = 17.560(8),b = 10.528(5),c = 30.613(15) ,V = 5659(5) 3,Z = 4,Dc = 1.430 g/cm3,F(000) = 502,μ = 0.739 mm-1,R = 0.0902,wR = 0.1346(I 2σ(I)),S = 1.002.Crystal data of 2:C24H16CuN2O5,Mr = 475.93,monoclinic,space group P21/n,a = 9.8904(13),b = 11.0782(16),c = 18.321(3) ,β = 11.0782(16)°,V = 1993.8(5) 3,Z = 4,Dc = 1.585 g/cm3,F(000) = 972,μ = 1.137 mm-1,R = 0.0433,wR = 0.0723(I 2σ(I)) and S = 1.004.Compound 1 displays a one-dimensional(1D) zigzag chain structure constructed from phen ligands and the deprotonated ligands of L2-,which further forms a ladder-shaped supramolecular architecture via the bridge of 4,4'-bpy ligand.Complex 2 also possesses a ladder-shaped architecture based on the dinuclear CuII units. 展开更多

One new coordination polymer based on 4-[(8-hydroxy-5-quinolinyl)azo]-benzoic acid(H2L), { [CdL(H20)]·H2O}n(1) was solvothermally synthesized and structurally characterized by single-crystal X-ray diffrac... One new coordination polymer based on 4-[(8-hydroxy-5-quinolinyl)azo]-benzoic acid(H2L), { [CdL(H20)]·H2O}n(1) was solvothermally synthesized and structurally characterized by single-crystal X-ray diffrac- tion, infrared spectrometry, elemental analysis, powder X-ray diffraction(PXRD) and thermogravimetric analysis (TGA). In compound 1, L2- ligands link Cd(II) to form a sinusoidal ruffling layer, in which the carboxylic groups connect Cd(II) into an infinite Cd--O chain. And the layers are further stabilized by hydrogen bonding and π-π in- teractions, forming a three-dimensional(3D) supramolecular network. In addition, the fluorescent property of compound 1 was also investigated. 展开更多
