{4,4',5,5'-Tetra-methyl-2,2'-[1,1'-(ethane-1,2-diyldinitrilo)diethyl-idyne]diphenolato}nickel(II)-methanol-chloro-form (1/1/1).

ABSTRACT: In the title compound, [Ni(C(22)H(26)N(2)O(2))]·CH(3)OH·CHCl(3), the Ni(II) ion is in a slightly distorted square-planar geometry involving an N(2)O(2) atom set of the tetra-dentate Schiff base ligand. The asymmetric unit contains one mol-ecule of the complex and one mol-ecule each of chloro-form and methanol. The methanol mol-ecule is hydrogen bonded to the phenolate O atoms. In the crystal structure, short inter-molecular distances between the centroids of six-membered chelate rings [3.7002?(9)?Å] indicate the presence of ?-? inter-actions, which link the mol-ecules into stacks along the a axis. In addition, there are Ni?Ni distances which are shorter than the sum of the van der Waals radii of two Ni atoms. The crystal structure is further stabilized by inter-molecular O-H?O and C-H?O hydrogen bonds, and weak inter-molecular C-H?? inter-actions linking mol-ecules into extended one-dimensional chains along the c axis.
