a monomeric structure. The gallium hydride syn-GaH[P2N2] (5) is synthesized by the addition of LiGaH4 to syn-MCl[P2N2] (M=Ga (2), In (3)). This species is unstable and could only be characterized in solution. Reduction of syn-MCl[P2N2] (M=Ga (2), In (3)) with KC8 yields the reduced, dimeric species syn-M[P2N2]}2 (M=Ga (6), In (7)). The solution 1H- and 31P1H}-NMR spectra are consistent with C2v symmetric

氯化物syn -MCl [P 2 N 2 ](M = Al(1),Ga(2),In(3))中导致
氢化铝syn -AlH [P 2 N 2 ](4)。溶液的1 H-和31 P 1 H} -NMR光谱与溶液中的C 2 v对称物质一致。X射线晶体结构显示出
氢化物是单体,没有与盐(LiCl)或外部碱(Et 2O)。在固态下发现大环的两个膦与
金属中心的配位。溶液分子量测量与单体结构一致。
氢化镓syn -GaH [P 2 N 2 ](5)是通过将LiGaH 4添加到syn -MCl [P 2 N 2 ](M = Ga(2),In(3))而合成的。该物种不稳定,只能在溶液中表征。用KC 8还原syn -MCl [P 2 N 2 ](M = Ga(2),In(3))产生还原的二聚体物种 syn -M [P 2 N 2 ]} 2(M = Ga(6),In(7))。溶液的1 H-和31
