NaSm(PO(3))(4) has been prepared by solid state reactions. It belongs to type II of the structural family of M(I)Ln(III)(PO(3))(4) compounds (M(I) = alkali metal and Ln(III) = rare earth metal) and is composed of (∞)(PO(3))(n)](n-) polyphosphate chains with a repeating unit of four PO(4) tetra-hedra. The chains extend parallel to [100] and share O atoms with irregular SmO(8) polyhedra, forming a three-dimensional framework which delimits tunnels occupied by Na(+) cations in a distorted octa-hedr ...[more]
