Bis(?(2)-?:?-2,4,6-trimethyl-benzonitrile)-bis-[(N-isopropyl-3,5-dimethyl-anilido)molybdenum(III)](Mo-Mo).

ABSTRACT: The title compound, [Mo(2)(C(11)H(16)N)(4)(C(10)H(11)N)(2)], is a dinuclear molybdenum complex with a formal metal-metal bond [Mo?Mo separation = 2.5946?(8)?Å], four anilide-type ligands and two bridging mesityl nitrile groups. There are two inversion symmetric mol-ecules in the unit cell (an inversion center is localized at the mid-point of the Mo-Mo bond), each with approximate non-crystallographic C(2h) symmetry. The mol-ecules contain disordered isopropyl and 3,5-C(6)H(3)Me(2) groups on different anilido ligands; the major component having an occupancy of 0.683?(7). The complex was obtained in low yield as the product from the reaction between the bridging pyrazine adduct of molybdenum tris--anilide ([?(2)-(C(4)H(4)N(2)){Mo(C(11)H(16)N)(3)}(2)]) and mesityl nitrile with a loss of one anilido ligand.
