Diaquabis(4-bromo-benzoato-κO)-bis(N,N'-diethyl-nicotinamide-κN)zinc(II)
Abstract:
The title compound, [Zn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], is a monomeric complex with the Zn(II) atom lying on an inversion center. It contains two 4-bromo-benzoate, two diethyl-nicotinamide ligands and two water mol-ecules, all of which are monodentate. The four O atoms in the equatorial plane around the Zn atom form a slightly distorted square-planar arrangement, while the distorted octa-hedral geometry is completed by two N atoms in the axial positions. The methyl group of one of the ethyl groups is disordered over two positions, with occupancies of ca 0.65 and 0.35. The two aromatic rings are oriented at an angle of 77.22 (14)°. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into chains along the a axis.
