{4,4 ',6,6 '-Tetrachloro-2,2 '-[2,2-dimethylpropane-1,3-diylbis(nitrilomethanylyl-idene)]diphenolato}dioxidomolybdenum(VI)

The asymmetric unit of the title compound, [Mo(C19H16Cl4N2O2)O-2], comprises two independent molecules (A and B). The geometry around the Mo-VI atom is distorted octahedral in each complex molecule, supported by two oxide O atoms and the N2O2 donor atoms of the coordinating ligand. The dihedral angle between the benzene rings is 74.96 (11) angstrom for molecule A and 76.05 (11) angstrom for molecule B. In the crystal, the B molecules are linked by pairs of C-H center dot center dot center dot Cl hydrogen bonds, forming inversion dimers. The crystal structure is further stabilized by C-H center dot center dot center dot pi interactions. An interesting feature of the crystal structure is a Cl center dot center dot center dot Cl contact [3.3748 (18) angstrom], which is shorter than the sum of the van der Waals radii of Cl atoms (3.50 angstrom).
