Diaqua-bis-(2-bromo-benzoato-κO)bis-(N,N-diethyl-nicotinamide-κN)cobalt(II).

ABSTRACT: In the mononuclear title compound, [Co(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Co(II) ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 2-bromo-benzoate anion, one diethyl-nicotinamide (DENA) ligand and one coordinated water mol-ecule; 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 octa-hedral coordination is completed by the two pyridine N atoms of the DENA ligands in axial positions. The dihedral angle between the carboxyl-ate 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, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
