Derivatives of [GaX2(dmpe)(2)][GaX4] (X = Cl, Br, I) were prepared and characterized. The salts contain a cation involving two diphosphine ligands bound to GaX2+, imposing a pseudo-octahedral geometry at gallium. A variety of possible structural alternatives for the equimolar combination of GaX3 and dmpe have been computationally modelled and shown to be energetically similar to the observed cations, indicating potential fluxionality in the system, and are in agreement with spectroscopic characterization.
