N2 - The oxohydrazido-complexes [MoO(NNR2)(S2CNR′2)2] [R2 = Me2, MePh, or (CH2)5; R′2 = Me2, Et2, or (CH2)5] react with an excess of acids HX (X = Cl, Br, SPh, 1/2 1,2-O2C6H4, or 1/2 2,3-S2C6H3CH3) to give seven-co-ordinate [MoX2(NNR2)(S2CNR′2) 2]. For X = Cl or Br these complexes react with NaS2CNR′2 to give the cationic seven-coordinate [Mo(NNR2)(S2CNR′2)3] +. The complex [MoO(NNMe2)(C9H6NO)2] gives NHMe2, NH3, and Me2NNH2 on reaction with HCl and an X-ray crystal structure shows a significantly bent NNMe2 ligand with MO-N-N 155.5°. The MO-N and N-N distances of 1.800(9) and 1.28(1) Å lie within the range found for other hydrazido(2-)-complexes. The complex ctystallises in the space group P21/a with a = 19.00(5), b = 14.59(4), c = 7.26(2) Å, and γ = 102.90(6)° for Z = 4. The final conventional error index, R, is equal to 0.087 for 2 747 reflections.
