Crystal Structure of a Novel Coordination Polymer of 4-Bromobenzoic Acid with Cobalt(II)

Abstract

A novel coordination polymer of cobalt(II) with 4-bromobenzoic acid ligand was synthesized. The title complex was crystallized in a monoclinic system, space group P2₁/n with a = 15.396(3)Å, b = 5.8802(12)Å, c = 27.374(6)Å, β = 101.16(3)°, V = 2431.4(9)ų, Z = 4. The central Co(II) atoms are six-coordinated by four O atoms and two N atoms, giving approximately octahedral environments. In the crystal packing of the title complex, molecules are connected by O-H…O hydrogen bonds, forming a linear polymeric chain parallel along the b axis.
