Abstract

The title compound, [Mo2(C11H16N) 4(C10H11N)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 molecules in the unit cell (an inversion center is localized at the mid-point of the Mo - Mo bond), each with approximate non-crystallographic C2h symmetry. The molecules contain disordered isopropyl and 3,5-C6H3Me2 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 ([μ2- (C4H4N2){Mo(C11H16N) 3}2]) and mesityl nitrile with a loss of one anilido ligand.
