Description
Summary:The title compound, a GaII dimer, [Ga2Br4(C12H23P)2], was synthesized by reaction of GaBr(THF)n (THF is tetrahydrofuran) with dicyclohexylphosphine in toluene. At 150 K the crystallographically centrosymmetric molecule exhibits disorder in which one of the two independent cyclohexyl groups is modelled over two sites in a 62 (1):38 (1) ratio. In d6-benzene solution, the compound exhibits virtual C2h symmetry as determined by 1H NMR. The coordination environment of the GaII atom is distorted tetrahedral.
