Abstract
A new coordination polymer, {[Cd(bbmb)(bdc)]} n (bbmb = 1,1′-(1,4-butanediyl)bis-(2-methylbenzimidazole), H2bdc = 1,3-benzenedicarboxylic acid) was synthesized under hydrothermal conditions. The complex was structurally characterized by single crystal X-ray diffraction analyses, infrared spectroscopy (IR), elemental analyses. The compound crystallizes in the monoclinic system, space group P21/c with a = 10.860(6) Å, b = 13.115(7) Å, c = 21.009(9) Å, β = 120.94(2)°, V = 2567(2) Å3, Z = 4, C28H26CdN4O4, M r = 594.93, D c = 1.540 g/cm3, μ = 0.893 mm–1. Each cadmium center is six coordinated with four O atoms from two bdc2– anions, and two N atoms of two bbmb ligands. The complex features a 4-connected 2D (4, 4) sheet with a point symbol {42.62}. Fluorescence properties of the title complex were investigated.
