1,2-Mo2Me2NMe24 reacts in hydrocarbon solvents with 1,3-di-p-tolyl-triazine, C7H8NNNHC7H8, to give the title compound as a red crystalline solid. An X-ray study shows that in the solid state, the molecule has a crystallographically imposed C2 axis of symmetry. The MoMo bond, 2.1741angstroms, is bridged by a cis-pair of triazenido ligands which afford sufficient flexibility to allow a non-eclipsed geometry. Each molybdenum atom is coordinated to three nitrogen atoms and one carbon atom which roughly lie in a plane. Pertinent bond distances are Mo-C methyl 2.1934 angstroms, Mo-N dimethylamido 1.9483 angstroms, Mo-N triazinido 2.1573 and 2.2833 angstroms, with the longer distance associated with the Mo-N bond which is trans to the Mo-CH3 bond. These observations are compared with other findings in dimolybdenum and ditungsten chemistry MM. Crystal data for Mo2Me2NMe22-C7H8N3C7H82 are a 21.6085 angstroms, b 9.4402 angstroms, c 24.0766 angstroms, 135.491, V 3442.51 angstromscubed, Z 4, d sub calcd 1.464 g cc and space group C2c. Author
