Bi2O3-CuO-P2O5 system: Two novel compounds built from the intergrowths oxocentered polycationic 1D-ribbons

This paper reports the crystal structure of two new bismuth oxophosphate compounds. Both are built on the association of n=3 and 4 building unit ribbons surrounded by isolated PO4 tetrahedra and tunnels hosting Cu2+ cations. They come in addition to the numerous Bi-based compounds already pointed out. Once more, this is the proof of the richness of this crystal system.
