Özet

In the mononuclear title compound, [Co(C7H4BrO2)(2)(C10H14N2O)(2)(H2O)2], the Co-II 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 Co-II 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)degrees; the pyridine and benzene rings are oriented at a dihedral angle of 43.64 (6)degrees. In the crystal structure, intermolecular O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network.
