Peroxofluorokomplexe der Übergangsmetalle, V [1-3] Kristallstruktur von K2Ti(O2)F4 · H2O (orange) mit einem Di(μ-fluoro)diperoxo-hexafluorodititanat(IV)-Anion / Transition Metal Peroxofluoro Complexes, V [1-3] Crystal Structure of K2Ti(O2)F4 · H2O (orange) with a Di(μ-fluoro)diperoxo-hexafluorodititanate(IV) Anion

Abstract

Orange crystals of K2Ti(O2)F4 · H2O have been obtained from aqueous solution. The crystal structure (space group P21/n, a = 604.3(3), b = 1424.6(4), c = 761.0(2) pm, β = 103.98°, Z = 4, dc = 2.63 gcm-3, dm = 2.62 gcm-3, R = 0.051 for 2257 independent reflections) shows isolated di(μ-fluoro)-bridged [Ti2(O2)2F8]4- anions, which are inter­connected by hydrogen bonded H2O forming infinite chains.
