摘要：
[Zr2F8(dmso)(2)(H2O)(2)], a dehydration product of [ZrF4(dmso)(H2O)(2)]center dot 2H(2)O, crystallizes in the orthorhombic symmetry [space group Cmca, a=7.8266(3) angstrom, b=13.5847(5) angstrom, c=15.6119(6) angstrom, and Z=4]. The structure, solved ab initio in direct space from X-ray powder diffraction data, is built up from [Zr2F8O4] bipolyhedra formed by edge sharing of [ZrF5O2] pentagonal bipyramids (condensed from isolated [ZrF4O3] pentagonal bipyramids in the precursor). Difficulties associated with a fortuitous hexagonal pseudosymmetry were surmounted. The dmso departure at 220 degrees C leads to an amorphous phase.
