Abstract:

A hydrothermal reaction of 1,3,5-benzene-tricarboxylic acid (H 3BTC) with cadmium acetate, zinc acetate and pyridine led to the formation of pink crystals of [Cd2Zn(BTC)2-(H 2O)4]n·2nH2O 1. Single-crystal X-ray diffraction analysis has revealed that 1 (Cd 2ZnC18H18O18) crystallizes in the monoclinic system, space group C2/c with a = 19.4328(7), b = 7.1420(3), c = 18.0426(5) Å, β = 118.035(1)°, V = 22.10.3(1) Å3, Mr = 812.49, Dc = 2.442 g/cm 3, Z = 4, μ(MoKα) = 3.081 mm-1 and F(000) = 1584. A total of 10735 reflections were collected, of which 2544 were unique. The structure was refined to R = 0.0200 and wR = 0.0603 for 2388 observed reflections with I>2σ(I). The crystal structure consists of cadmium(II)/zinc(II) carboxylates of BTC as well as coordination and discrete water molecules. Extension of the coordination geometry around three metal centers (Cd(1), Cd(2) and Zn(1)), two BTC3- ligands and four coordinated water molecules generates a three-dimensional coordination polymer.
