Abstract
The asymmetric unit of the title compound, [Ni(C19H16I4N2O2)], comprises half of a Schiff base complex. The NiII atom is located on a twofold rotation axis which also bisects the central C atom of the 2,2-dimethylpropane group of the ligand. The geometry around the NiII atom is distorted square-planar, with a dihedral angle of 21.7 (3)° between the symmetry-related N/Ni/O coordination planes. The dihedral angle between the symmetry-related benzene rings is 27.9 (3)°. In the crystal, short intermolecular I⋯I [3.8178 (9) and 3.9013 (10) Å] interactions are present.
Highlights
The NiII atom is located on a twofold rotation axis which bisects the central C atom of the 2,2-dimethylpropane group of the ligand
The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry
R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger
