Pentaaquahydroxoscandium(III) dibromide, [Sc(H2O)5(OH)]Br2

U. Kolitsch

Abstract: [Sc(H2O)5(OH)]Br2 is a scandium(III) halide compound that contains centrosymmetric [Sc(H2O)5(OH)]24+ dimeric cationic units built from two edge-sharing (hydroxo-bridged) symmetrically equivalent Sc(H2O)5(OH)2 polyhedra. The mean Sc-O bond length is 2.156 Å. The hydrogen bonds (O...Br) are of low strength. All atoms are in general positions.
