Diaqua­Bis­(2-Bromo­Benzoato-Κo)Bis­(N,N-Diethyl­Nicotinamide-Κn1)Cobalt(Ii)

Abstract

In the mononuclear title compound, [Co(C7H4BrO2)2(C10H14N2O)2(H2O)2], the CoII ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 2-bromo­benzoate anion, one diethyl­nicotinamide (DENA) ligand and one coordinated water mol­ecule; all ligands are monodentate. The four O atoms in the equatorial plane around CoII form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two pyridine N atoms of the DENA ligands in axial positions. The dihedral angle between the carboxyl­ate group and the attached benzene ring is 84.7 (1)°; the pyridine and benzene rings are oriented at a dihedral angle of 43.64 (6)°. In the crystal structure, inter­molecular O—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network.
