title: The reaction of 'GaI' with a 1,3-diyne: synthesis, characterisation and reactivity of a novel C-C coupled ene-diyne-bis(gem-organodigallium(III)) complex.
abstract: Treatment of 'GaI' with a 1,3-diyne, Me3SiC[triple bond]CC[triple bond]CSiMe3, leads to C-C coupling reactions and the isolation of the novel organogallium species, [Ga4I8[C8(SiMe3)4]], as two isomeric forms; their X-ray crystal structures show them to contain the first structurally authenticated gem-organodigallium fragments and to exhibit rare examples of Ga-alkyne pi-interactions.
