A Novel 3D Cd-II-CP Based on a Bi-functional (N-/O-Sites) Triazole-modified Carboxyl Ligand: Structure, Topology and Photoluminescence

With triazole-modified derivative as link, one new framework [Cd-5(mu(5)-HL2-)(2)(mu(4)-L3-)(2)(H2O)(10)]center dot 2H(2)O (1,H3L = 2-(1,2,4-triazol-1-yl)benzene-1,3,5-tricarboxylic acid) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, powder X-ray diffraction and elemental analysis. Complex 1 exhibits a 3D (3,4,6)-connected net cross-linked by binuclear [Cd-2(COO)(5)](-) cluster and mononuclear Cd(II) geometry via HL2-/L3- ligands. It crystallizes in triclinic system, space group P-1(-) with a = 7.7411(11), b = 9.8813(15), c = 20.177(3) angstrom, alpha = 85.547(4)degrees, beta = 80.603(4)degrees, gamma = 67.976(3)degrees, V = 1411.3(4) angstrom(3) , Z = 1, M-r = 1876.89 g/mol, D-c = 2.208 mg/m(3), mu = 1.97 mm(-1), F(000) = 918, GOOF = 1.03, the final R = 0.0869 and wR = 0.1950 for 3127 observed reflections with I> 2 sigma(I). The solid photoluminescent behaviour of 1 has been further functionally investigated.
