Abstract
A novel Mg6 cluster molecule with the formula of Mg6(μ 3-OH)2(μ 3-Br)2(μ-Br)8(THF)8 (1) has been isolated in 38% yield from a reaction of the Grignard reagent, 2-naphthyl-Mg-Br with BBr3 in THF. The structure of 1, determined by a single-crystal X-ray diffraction analysis, contains two Mg3 triangles linked together by two bridging bromide ligands. Within each Mg3 triangle, one hydroxide and one bromide ligand function as triply bridging ligands capping both sides of the Mg3 triangle. The coordination geometry around each Mg(II) ion is approximately octahedral. NMR studies revealed that compound 1 is highly fluxional in solution.
