摘要:
                                The reaction of [Mo2Cl4(mu-S2)(mu-2-SC5H3NH-3-SiMe3)(2-SC5H3N-3-SiMe3)2] with phenylhydrazine yields [Mo(NNPh)(2-SC5H3N-3-SiMe3)3] (1).  Complex 1 adopts a pentagonal bipyramidal geometry with the phenyldiazenido group occupying an axial position.  The structural parameters exhibited by 1 are similar to those of other members of the class of seven coordinate Mo-hydrazido and Mo-diazenido species.  Crystal data for C30H41N5Si3S3Mo (1):  monoclinic space group P2(1)n, a = 11.600(2), b = 14.880(3), c = 21.681(3) angstrom, beta = 90.46(1)degrees, V = 3242.2(12) angstrom 3, Z = 4; 5690 reflections, R = 0.049.
