Abstract

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.
