“…Thiobenzoylhydrazine is also capable of displacing a thiohydroxamate ligand and shows a pronounced tendency to chelate to Mo, which constrasts with the monodentate coordination mode displayed by PhC(0)NHNH2 in the present derivatives, although there are examples known of chelating benzoylhydrazines. 33 One of the most significant results of the present study has been the characterization of the first end-on-bonded -NHNHR species in complex I. We are currently investigating the reactivity of this compound toward protonation with particular interest in (i) a comparison of its reactivity with that of the diazenido group and (ii) the characterization of reaction products and intermediates, which hopefully will shed light on the reactivity of the Mo-NHNHR group.…”

The reaction of benzoylhydrazine with the molybdenum thiohydroxamate complex [MoO,(PhC(S)N(Me)O),] yields complex I, [MO(N,C(O)P~)(NHNHC(O)P~)(P~C(S)N(M~)~)~].O.~H~O. Cr stals of I (C30H29M~N604.5S2) are monoclinic, space group P2,/c, with a = 18.968 (6) A, b = 13.900 (4) A, c = 12.629 (3) 1, +3 = 107.90 (2)O, and Z = 4. The last blocked-matrix least-squares refinement, when the absorption correction data were used, converged with R = 0.029 and R, = 0.030. The complex contains a diazenido group and an "end-on"-bonded hydrazide( 1-) group together with two bidentate thiohydroxamate ligands in the coordination sphere around Mo. This is the first structurally characterized end-on hydrazido(1-) complex containing the NH-NH group. Both hydrogens were located in the refinement. Selected dimensions for this group are Mo-N = 1.938 (4) A, N-N 5'1.361 (7) A, and Mo-N-N = 131.9 (3)O. The corresponding dimensions for the diazenido group are quite different, and they are respectively 1.758 (5) A, 1.292 (7) A, and 168.8 (4)O. The 'H NMR spectrum of I shows coupling between the two hydrogens on the hydrazido(1-) group with doublets centered at 15.85 and 12.51 ppm. When the same dioxomolybdenum thiohydroxamate complex is reacted with thiobenzoylhydrazine, the complex 11, [Mo(NHNC(S)Ph)(N,C(S)Ph)(PhC(S)N-(Me)O)], is formed. Complex I1 of formula C22H,9M~N50S3 crystallizes in the triclinic space group P i , with a = 11.728 (4) A, b = 11.744 (3) A, c = 11.860 (5) A, a = 60.27 (3)O, +3 = 60.57 (3)O, and y = 64.80 (3)'. The final blocked-matrix refinement converged with R = 0.024 and R, = 0.028. The complex possesses a distorted six-coordinate structure with three different bidentate ligands: diazene, diazenido, and thiohydroxamate. The hydrogen atom of the diazene group was found attached to the nitrogen bonded to Mo. Bond distances in the diazene group include Mo-N = 1.972 (3) A and N-N = 1.343 (6) A and for the diazenido group Mo-N = 1.789 (4) and N-N = 1.324 (6) A. Reaction of the corresponding hydroxamate complex [MoO,(PhC(O)N-(Me)O),] with thiobenzoylhydrazine led to substitution of all the initial ligands to produce the known trischelated thiobenzoyldiazene species [Mo(NHNC(S)Ph),].
