hydrazido(2−) complexes such as [WI(NNH)(dpe)2] and [WI2(NNH2)(PMe2Ph)3] from [WI(NNSiMe3)(dpe)2] and mer-[WI2(NNHSiMe3)(PMe2Ph)3], respectively. When reduced with excess Na in THF under N2, complexes trans-[MI(NNSiMe3)(PMe2Ph)4] (M=Mo or W) and mer-[WI2(NNHSiMe3)(PMe2Ph)3] gave (Me3Si)2NH and NH3 in substantial yields, accompanied by the regeneration of the parent dinitrogencomplexes.

The coordinateddinitrogen in the W(P–P) complex can be protonated using protons from H2, split into protons and hydrides using the frustrated Lewis pair concept, under normal experimental conditions (room temp., 1 atm). The reaction progress of the N2 protonation was monitored by spectroscopic and analytical techniques.
Syntheses, Structures, and Reactivities of Heterobimetallic Bridging Dinitrogen Complexes Containing Group 6 and Group 4 or 5 Transition Metals<sup>1</sup>
heterobimetallic dinitrogen complexes containing group 6 and group 4 or 5 transition metals were synthesized by the reaction of the tungsten or molybdenum dinitrogen complexes cis-[W(N2)2(PMe2Ph)4] (1) and trans-[M(N2)2(dppe)2] (2) (M = W, Mo) with group 4 or group 5 compounds such as [CpTiCl3], [Cp2M‘Cl2] (M‘ = Ti, Zr, Hf), or [Cp‘M‘Cl4] (Cp‘ = Cp, Cp*; M‘ = Nb, Ta). Crystallographic studies of the complexes thus

We have prepared and characterized a series of unprecedented group 6–group 11, N2-bridged, heterobimetallic [ML4(η1-N2)(μ-η1:η1-N2)Au(NHC)]+ complexes (M = Mo, W, L2 = diphosphine) by treatment of trans-[ML4(N2)2] with a cationic gold(I) complex [Au(NHC)]+. The adducts are very labile in solution and in the solid, especially in the case of molybdenum, and decomposition pathways are likely initiated
