isolation of the corresponding adducts [MoO(N3)3⋅2 CH3CN] and [WO(N3)4⋅CH3CN]. Subsequent reactions of [MoO(N3)3] with 2,2′‐bipyridine and [PPh4][N3] resulted in the formation and isolation of [(bipy)MoO(N3)3] and [PPh4]2[MoO(N3)5], respectively. Most molybdenum(V) and tungsten(VI) oxoazides were fully characterized by their vibrational spectra, impact, friction and thermal sensitivity data and, in the case
从[MOF 4 ](M = Mo,W)和Me 3 SiN 3出发,制备了一系列新型的钼(V)和钨(VI)含氧叠氮化物。尽管Me 3 SiN 3与WOF 4在SO 2溶液中的反应是通过氟-叠氮化物交换形成的[WO(N 3)4 ] ,但与MoOF 4的反应导致Mo VI还原为Mo V并形成了[MoO(N 3)3 ]。在乙腈溶液中进行,这些反应导致分离出相应的加合物[MoO(N 3)3⋅2CH 3 CN]和[WO(N 3)4 ⋅CH 3 CN]。[[MoO(N 3)3 ]与2,2'-联吡啶和[PPh 4 ] [N 3 ]的随后反应导致[(bipy)MoO(N 3)3 ]和[PPh 4 ]的形成和分离。2分别为[MoO(N 3)5 ]。最钼(V)和钨(VI)oxoazides得到充分特征在于它们的振动光谱,冲击,摩擦和热灵敏度数据,并在[WO(N的情况下3)4 ⋅CH 3 CN],[(联吡啶)的MoO
