Diaquabis(2-bromobenzoato-κO)bis(N,N-diethylnicotinamide- κN¹)cobalt(II)

In the mononuclear title compound, [Co(C₇H₄BrO ₂)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)°; 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.
