Dimeric piperidino-alane and -gallane: metal hydrides with a cyclic M(μ-N)2M core (M = Al or Ga)

Abstract

The crystal structures of piperidino-alane and -gallane at 150 K have each been shown to consist of dimeric molecules [[upper bond 1 start]CH2(CH2)4N[upper bond 1 end]MH2]2 centred on a planar, nearly square M(μ-N)2M core (M = Al or Ga). The molecular structures thus contrast with the hydrogen-bridged units favoured by the sterically encumbered piperidino derivatives {[[upper bond 1 start]CMe2(CH2)3CMe2N[upper bond 1 end]]AlH2}3 and {[[upper bond 1 start]CMe2(CH2)3CMe2N[upper bond 1 end]]2AlH}2 and are also compared with those of other amido derivatives of the Group 13 hydrides.
