title: Tetra-bromidobis(dicyclo-hexyl-phosphane-κP)digallium(Ga-Ga).
abstract: The title compound, a Ga(II) dimer, [Ga(2)Br(4)(C(12)H(23)P)(2)], was synthesized by reaction of GaBr(THF)(n) (THF is tetra-hydro-furan) with dicyclo-hexyl-phosphine in toluene. At 150 K the crystallographically centrosymmetric molecule exhibits disorder in which one of the two independent cyclo-hexyl groups is modelled over two sites in a 62 (1):38 (1) ratio. In d(6)-benzene solution, the compound exhibits virtual C(2h) symmetry as determined by (1)H NMR. The coordination environment of the Ga(II) atom is distorted tetrahedral.
