Abstract
The reactions of [M(N2)2(L–L)2][M = Mo or W; L–L = diphosphine = Et2PCH2CH2PEt2(depe) or (4-MeOC6H4)2PCH2CH2P(C6H4OMe-4)2(dmppe)] with acids HX (X = Cl or Br) yield various products. Those containing nitrogen include [MHX(NNH2)(L–L)2]2+, and [MX(NNH2)(L–L)2]+, but the course of the reaction is also solvent dependent. The crystal structure of the complex [WBr(NNH2)(Et2PCH2CH2PEt2)2]Br·0.5MeOH is described.Keywords
