Abstract (EN):
In the title complex, trans-(2,2'-[cyclohexane-1,2-diylbis(nitrilomethylidyne)]diphenolato-kappa O-4,N,N',O')nickel(II)-chloroform (1/1), [Ni(C20H20N2O2)]. CHCl3, the Ni atom has a square-planar geometry, slightly tetrahedrally distorted. The Ni-N and Ni-O bonding distances are within the expected ranges for Ni-Schiff base derivatives. The diimine bridge has a gauche conformation with the cyclohexyl ring almost coplanar with the NiN2O2 plane. The complex molecules pack in dimers with an Ni . . . Ni distance of 3.59 (1) Angstrom and form a three-dimensional structure displaying a herring-bone configuration. Channels are occupied by solvent molecules, which are involved in C-H . . .O hydrogen bonds with the ligand O atoms.
