Steric effects in the reversible oxygenation of cobalt–Schiff-base complexes. Part III. Crystal and molecular structure of the meso-form of NN′-cyclohexylenebis(salicylideneiminato)cobalt( II )

The crystal structure of the title compound has been determined from three-dimensional X-ray data by Fourier methods and refined by the anisotropic least-squares method to a final R of 0·046 using 1979 independent reflections. Crystals are monoclinic, space group P21/c, with cell parameters a= 12·320(9), b= 24·200(10), c= 12·260(9)Å, and β= 108·07(9)°, Z= 8. The two Crystallographically independent molecules are geometrically similar, the cobalt atom having a square-planar stereochemistry slightly tetrahedrally distorted.
