Diaqua-bis(N,N-diethyl-nicotinamide-κN)bis-[4-(dimethyl-amino)benzoato-κO]nickel(II).

ABSTRACT: The centrosymmetric title Ni(II) complex, [Ni(C(9)H(10)NO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains two dimethyl-amino-benzoate (DMAB), two diethyl-nicotinamide (DENA) ligands and two water mol-ecules, all of them monodentate. The four O atoms in the equatorial plane around the Ni(II) atom 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 Ni(II) atom is displaced by 0.681 (1) Å out of the least-squares plane of the carboxyl-ate group. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 5.61 (7)°, while the pyridine and benzene rings are oriented at a dihedral angle of 73.20 (4)°.
