Ba 2 Cu 2 AlF 11 is trigonal: a = 7.301(1) Å, c = 14.145(2) Å, γ = 120°, Z = 3. The crystal structure was solved in the space group P3 2 (n° 145), from X‐ray single crystal data using 2675 unique reflections (2476 with F/σ(F) > 4). It consists in a complex tridimensional arrangement of copper‐fluorine and aluminium‐fluorine octahedra, with an original kind of linkage which involves simultaneously edges and vertices.
