摘要：
By the addition of different secondary ligands, three new D-10 metal coordination polymers, [M-2(ET)(pzdc)(mu(3)-OH)] [M =Cd(1), Zn(2)] and [Zn(Et)(Hbic)] (3) (ET = 5-thyltetrazole; H(2)pzdc = Pyrazine-2,3-dicarboxylic acid; Hbic = 1H-benzimidazole-5-carboxylic acid), have been successfully prepared under hydrothermal reactions and structurally characterized by single-crystal X-ray diffraction analysis. The ET ligand in compounds 13 is in situ generated from the [2 + 3] cycloaddition reaction of the precursor propionitrile and NaN3 in water with the aid of zinc/cadmium salt. Compounds 1 and 2 present three-dimensional (3D) (4,4,4,4)-connected net based on O-centered M-3 isosceles triangle. Compound 3 exhibits a 3D diamond framework constructed by infinite -ET-Zn-ET- 1D zigzag chains and Hbic as bridging coligand. Furthermore, the thermal stabilities of compounds 1-3 and the luminescence properties of compounds 1 and 2 have been investigated. (c) 2012 Elsevier B.V. All rights reserved.
