Fluoride crystal structures. Part 28. Bis(tetraethylammonium)µ-oxo-bis[pentafluorotantalate(V)]

Abstract

The structure of the title compound has been determined by the heavy-atom method from 1 267 reflections, measured with a diffractometer, and refined by full-matrix least-squares methods to R 0.069. Crystals are monoclinic, space group P21/n, a= 8.57(1), b= 13.68(2), c= 11.79(2)Å, β= 96.1 (1)°, Z= 2. In the structure two tetraethylammonium ions counterbalance each [Ta2OF10]2– complex anion in which the two tantalum atoms are bridged by an oxygen atom (Ta–O 1.875 Å; Ta–O–Ta 180° by symmetry); the five remaining octahedral sites around each tantalum atom are occupied by fluorine atoms (mean Ta–F 1.90 Å).
