Structures of [Zr2F8(dmso)4] and [ZrF4(dmso)(H2O)2].2H2O

Abstract

μ-Difluoro-bis[bis(dimethyl sulfoxide)trifluorozirconium], [Zr 2 F 8 (dmso) 4 ], crystallizes in a monoclinic space group; the structure is built up from isolated [Zr 2 F 8 -(dmso) 4 ] bipolyhedra formed by edge sharing of [Zr 2 F 8 -(dmso) 2 ] pentagonal bipyramids. Diaqua(dimethyl sulfoxide)tetrafluorozirconium dihydrate, [ZrF 4 (dmso)-(H 2 O) 2 ] -2H 2 O, crystallizes as a triclinic structure composed of isolated [ZrF 4 (dmso)(H 2 O) 2 ] pentagonal bipyramids with two non-coordinated H 2 O molecules; the F-H and O-H hydrogen-bonding scheme has been determined
