Özet
The centrosymmetric title NiII complex, [Ni(C9H 10NO2)2(C10H14N 2O)2(H2O)2], contains two dimethyl-amino-benzoate (DMAB), two diethyl-nicotinamide (DENA) ligands and two water molecules, all of them monodentate. The four O atoms in the equatorial plane around the NiII 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)°. An intra-molecular O - H⋯O hydrogen bond results in the formation of a six-membered ring with a twisted conformation. In the crystal structure, inter-molecular O - H⋯O and C - H⋯O hydrogen bonds link molecules into a three-dimensional network. Two weak C - H⋯π inter-actions are also present. © 2009 Hökelek et al.
