Abstract
The title complex, [Ni(C12H11N2O2)2(C3H7NO)2], lies on on an inversion center. The NiII ion is coordinated in a slightly distorted octahedral 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-dimethylformamide ligands in the axial sites. In the crystal structure, weak intermolecular π–π stacking interactions with centroid–centroid distances of 3.7467 (13) Å link molecules into chains extending alongthe b axis.

The title complex, [Ni(C12H11N2O2)2(C3H7NO)2], lies on on an inversion center
As part of our onging studies of pyrazolone derivatives as potential ligands (Zhu et al, 2005; 2010a,b) we report the structure of the title complex, (I)
The NiII ion lies on a crystallographic inversion centre and adopts a slightly distorted octahedral coordination environment provided by four O atoms from two 4-acety-3methyl-1-phenyl-1H-pyrazol-5(4H)- onato ligands in the equatorial plane two O atoms from two N,N-bimethylformamide ligands in the axial sites
