(2,2'-Bipyridine-κN,N')[2-tert-butyl-anilinato(2-)]dichloridooxido-molybdenum(VI) dichloro-methane hemisolvate.

The Mo(VI) atom in the title structure, [Mo(C(10)H(13)N)Cl(2)O(C(10)H(8)N(2))]·0.5CH(2)Cl(2), has a distorted octa-hedral coord-ination sphere with cis-orientated oxide and imide ligands, trans-chloride ligands and the 2,2'-bipyridine (bipy) ligand N atoms lying trans to the oxide and imide ligands. An imide-ligand tert-butyl-methyl-group H atom makes a close approach with the oxide ligand (distance = 2.53 Å) and the imide-ligand N atom (distance = 2.41 Å). Another imide-ligand tert-butyl-methyl-group H atom makes a close approach to a chloride ligand (distance = 2.82 Å). One bipy-ligand α-H atom makes a close approach to the oxide ligand (distance = 2.4 Å) and the other α-H atom makes a close approach to the imide-ligand phenyl-ring ortho-H atom (distance = 2.52 Å). These close approaches suggest the presence of weak intra-molecular hydrogen bonds. The solvent molecule has been modelled under consideration of half-occupancy.
