Abstract

Composition space diagrams can be used to study the stability and variety of mixed transition metal oxide fluorides prepared under hydro(solvato)thermal conditions. Prior to this work the neutral (CuF(NC₅H₅)₄)₂NbOF₅ cluster had not been observed but it was expected because of the nucleophilic character of the oxygen and trans fluorine in the [NbOF₅]^2- species. [H₃O]₂[(CuF(NC₅H₅)₄)₂NbOF₅][F]₂, a compound containing the 2:1 (Cu: Nb) cluster, was synthesized from the concentration variables, [CuO·0.5 Nb₂O₅], [(HF)(χ)· pyridine], and [H₂O], by adding a fourth, [pyridine], and extending the composition space from a two-dimensional triangle to a three-dimensional prism. Crystal Data: [H₃O]₂[(CuF-(NC₅H₅)₄)₂NbOF₅][F]₂, tetragonal, space group I4₁/acd (no. 142), with a = 24.691(1) Å, c = 14.556(1) Å, Z = 8.
