Abstract
Ba3.75Nd9.5Ti18O54 is known to be an orthorhombic phase built of chains of octahedra parallel to the z axis with pentagonal, tetragonal and triangular tunnels between them. It is shown here that this phase is a representative of a family of orthorhombic phases related to the tetragonal tungsten bronzes (TTB). It is assumed that some of these new phases can be ferroelectric. Crystal chemical aspects of these phases are discussed.Keywords
