title: {4,4',6,6'-Tetrachloro-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methanylyl-idene)]diphenolato}dioxidomolyb-denum(VI).
abstract: The asymmetric unit of the title compound, [Mo(C(19)H(16)Cl(4)N(2)O(2))O(2)], comprises two independent mol-ecules (A and B). The geometry around the Mo(VI) atom is distorted octa-hedral in each complex mol-ecule, supported by two oxide O atoms and the N(2)O(2) donor atoms of the coordinating ligand. The dihedral angle between the benzene rings is 74.96 (11) Å for mol-ecule A and 76.05 (11) Å for mol-ecule B. In the crystal, the B mol-ecules are linked by pairs of C-H⋯Cl hydrogen bonds, forming inversion dimers. The crystal structure is further stabilized by C-H⋯π inter-actions. An inter-esting feature of the crystal structure is a Cl⋯Cl contact [3.3748 (18) Å], which is shorter than the sum of the van der Waals radii of Cl atoms (3.50 Å).
