Diaqua­Bis­(N,N-Diethyl­Nicotinamide-Κn1)Bis[4-(Dimethyl­Amino)­Benzoato-Κo]Cobalt(Ii)

Abstract

The title CoII complex, [Co(C9H10NO2)2(C10H14N2O)2(H2O)2], is centrosymmetric. It contains two dimethyl­amino­benzoate (DMAB) and two diethyl­nicotinamide (DENA) ligands and two water mol­ecules, all of them being monodentate. The four O atoms in the equatorial plane around the Co atom form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two pyridine N atoms of DENA ligands with the Co—N distance of 2.1519 (11) Å in the axial positions. The Co atom is displaced out of the least-squares plane of the carboxyl­ate group by −0.781 (1) Å. The dihedral angle between the carboxyl­ate group and the adjacent benzene ring is 5.05 (7)°, while the pyridine and benzene rings are oriented at a dihedral angle of 71.48 (5)°. In the crystal structure, inter­molecular O—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. Two weak C—H⋯π inter­actions are also present.
