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 ([μ(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.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.
Refinement. Methyl H atoms were placed in geometrically idealized positions allowing the initial torsion angle to be determined by a difference Fourier analysis [C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C)]. Other H atoms were placed in geometrically idealized positions and included as riding atoms [C—H = 0.93–0.98 Å and Uiso(H) = 1.2Ueq(C)]. Disordered i-Pr and disordered aryl group reside next to each other in the unit cell which causes a correlation in the model of the disorder, the ratios between the two components were refined freely. The geometries of the two PARTs of the disordered groups were kept similar using the SAME (it was applied for all atoms in the disordered i-Pr and disordered aryl groups) and SADI (it was used to restrain N2–C19A, N2–C19B and N3–C22A, N3–C22B bond distances) restraints of the program Shelxtl (Sheldrick, 2008) which allowed the 1,2- and 1,3- distances of corresponding atoms to be equal within determined standard deviations (0.02 Å for 1,2- and 0.04 for 1,3-distances); rigid bond restraints for anisotropic displacement parameters of atoms of the disordered i-Pr and disordered aryl group were applied using the DELU command (standart deviation is 0.01 Å). In addition, anisotropic displacement parameters of the pairs of overlapping disordered atoms of the major and minor components of the disorder were made equal using the EADP constraint.
