The molybdenum-molybdenum triple bond. 7. Bis(1,3-di-p-tolyltriazenido)tetrakis(dimethylamido)dimolybdenum

Mo2(NMe2)6 reacts in hydrocarbon solvents with 1,3-di-p-tolyltriazine, C7H8NNNHC7H8, to give the title compound, Mo2(NMe2)4(C7H8N 3C7H8)2, as a red, crystalline solid. An X-ray study shows that in the solid state each molybdenum atom is coordinated to four nitrogen atoms which lie in a plane; there is an unbridged molybdenum-to-molybdenum triple bond with a Mo-Mo distance of 2.212 (1) ?, and the molecule has crystallographically imposed C2 symmetry. Variable-temperature 1H NMR spectra recorded at 220 MHz support the view that this form of the molecule is present in solution. These observations are compared with other findings in dimolybdenum and ditungsten chemistry. Crystal data for Mo2(NMe2)4(C7H8N 3C7H8)2 are a = 27.529 (7) ?, b = 8.728 (2) ?, c = 18.294 (4) ?, β = 58.34 (1)°, V= 3741.58 ?3, Z = 4, dcalcd = 1.45 g cm-3, and space group C2/c.
