The title chain polymer compound, GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2), 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).
标题链状聚合物化合物[GaLi₂Br(C₃H₉OSi)₄(C₄H₈O)₂]ₙ是通过GaBr₃与Me₃SiOLi在甲苯/四氢呋喃中反应得到的。位于二重旋转轴上的Ga(III)原子由四个三甲基硅醇盐配体配位，具有扭曲的四面体几何构型。Li(I)原子由位于对称中心的一个桥连Br原子、两个三甲基硅醇盐配体和一个四氢呋喃分子以扭曲的四面体几何构型进行四配位。聚合物链沿[001]方向延伸。四氢呋喃分子在两个位置上无序，占位因子分别为0.57 (2)和0.43 (2)。
