Tetra­bromidobis(dicyclo­hexyl­phosphane-κP)digallium(Ga—Ga)

The title compound, a Ga^II 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 C_2h symmetry as determined by ¹H NMR. The coordination environment of the Ga^II atom is distorted tetrahedral.
