Hydrothermal Synthesis and Crystal Structure of a Cobalt Complex

Abstract

A new coordination polymer based on cobalt nitrate and 2-4-pyridyl-1H-benzimidazole- 5,6-dicarboxylate (H2pbd), namely [Co (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=7.6708(6)Å, b=8.0009(8)Å, c=12.8348(12)Å, α=96.4040(10) o, β=102.9480(10) o, γ=112.142(2) o, V=694.11(11)Å3, Z=1, C28H22CoN6O12 and F(000)=376.0. The H2pbd ligand links the Co (II) atoms into a double stranded chain.
