Abstract

The title complex, [Ni(C(12)H(11)N(2)O(2))(2)(C(3)H(7)NO)(2)], lies on on an inversion center. The Ni(II) ion is coordinated in a slightly distorted octa-hedral coordination enviroment by four O atoms from two bis-chelating 4-acety-3-methyl-1-phenyl-1H-pyrazol-5-olate ligands in the equatorial plane and two O atoms from two N,N-dimethyl-formamide ligands in the axial sites. In the crystal structure, weak inter-molecular π-π stacking inter-actions with centroid-centroid distances of 3.7467 (13) Å link mol-ecules into chains extending alongthe b axis.
