Synthesis and Structural Characterization of a Cobalt Coordination Polymer with Formate and Bis(4-(1H-imidazol-1-yl)phenyl)methanone Ligands

Resumo

A cobalt coordination polymer, {[Co(L¹)₂(H₂O)₂] · (HCOO)₂ · H₂O}_n, where L¹ is a bis(4-(1H-imidazol-1-yl)phenyl)methanone, has been synthesized and characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The crystal crystallizes in the triclinic sp. gr. \(P\bar {1}\) with the unit cell parameters a = 7.9504(6), b = 10.0231(7), c = 13.3129(8) Å, and α = 88.399(5)°, β = 75.310(6)°, γ = 79.179(6)°, Z = 1. The Co²⁺ ion has a distorted octahedral environment with two O atoms from two water molecules and four N atoms from four L¹ ligands. A thermal stability of polymer has been discussed.
