Hydrothermal Synthesis and Crystal Structure of a Cadmium Complex

Abstract

A new coordination polymer based on cadmium nitrate and 2-（4-pyridyl-1H-benzimidazole- 5,6-dicarboxylate (H2pbd) , namely [Cd( pbd)2•(H2O)2]n•n(H2O)2, have been synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectroscopy, and single crystal X-ray diffraction. The crystal of the complex crystallizes in triclinic, space group P-1 with a = 7.7200 Å, b = 8.1029Å, c = 13.0801Å, α= 96.1270(10) º, β = 102.1280(10)º, γ= 112.479(2) º, V = 723.15(12) Å3, Z =1, C28 H22 Cd N6 O12 and F(000) = 376.0. The H2pbd ligands links the Cd(II) atoms into a double stranded chain.
