Abstract
The phosphate niobium bronzes form a large family of structures charac terized by pentagonal or hexagonal tunnels. The host lattices of these oxides, involving a mixed valency of niobium Nb(V)-Nb(IV)-are describ ed here. The close relationships with pure octahedral structures, main ly perovskites, hexagonal tungsten bronzes (HTB) and tetragonal tungst en bronzes (TTB), and K3Nb8O21 are studied.
