Catena-Poly[[(tetra-hydro-furan-κO)lithium(I)]-bis-(μ-trimethyl-silanolato-κO:O)-gallium(III)-bis-(μ-trimethyl-silanolato-κO:O)-[(tetra-hydro-furan-κO)lithium(I)]-μ-bromido].

ABSTRACT: The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion centre, two trimethyl-silanolate ligands and one tetra-hydro-furane mol-ecule in a distorted tetra-hedral geometry. The polymeric chains extend along [001]. The tetra-hydro-furane mol-ecule is disordered over two positions with site-occupancy factors of 0.57 (2) and 0.43 (2).
