N2 - In the presence of Na2SO4, 1-methyl-1-phenylhydrazine and 1,1-diphenylhydrazine react with [MoO2(acac)2] to yield [Mo(NNMePh)2(acac)2] (1) and [Mo(NNPh2)2(acac)2] (2), respectively. Crystals of 1 are triclinic, space group P1̄, with unit cell dimensions a=9.780(6), b=11.134(11), c=13.504(7) Å, α=110.69(6), β=95.71(5), γ=111.70(7)° and Z=2. The structure was solved using 4317 unique observed reflections; the refinement of 299 variables gave R and Rw values of 0.059 and 0.067, respectively. Crystals of 2 are monoclinic, space group C2/c, with unit cell dimensions a=21.151(3), b=13.174(3), c=13.477(2) Å, β=123.17(1)° and Z=4. The structure was solved using 2760 unique observed reflections; the refinement of 195 variables gave R and Rw values of 0.039 and 0.040, respectively. In both complexes, the molybdenum atom displays distorted octahedral geometry with nearly linear cis-hydrazido ligands.
