Resumo

A new organic–inorganic zirconium (IV) fluoride, [C6N2H14]⋅(Zr2F10)⋅1.5H2O, is prepared by slow evaporation at 45 °C from a solution of Zr4+ and of 1,4-diazabicyclo[2.2.2]-octane (DABCO) in 40% aqueous HF. The structure, determined from single-crystal X-ray diffraction, is monoclinic, space group C2/m, a=19.598(8) Å, b=6.658(3) Å, c=10.891(3) Å, β=101.25(4)° and Z=4. Previously unknown ∞(Zr2F10)2− double chains, built up from edge-sharing ZrF7 pentagonal bipyramids and ZrF8 trigonal dodecahedra, are observed. The diprotonated organic cations, water molecules and the ∞(Zr2F10)2− chains are linked by hydrogen bonds.
