Abstract
Abstract A new vanadium phosphate containing sodium, NaV 3 P 3 O 12 , was prepared under reducing conditions. The compound is a paramagnetic insulator, having a Curie constant coincident with the one calculated for the the chemical formula NaV 2+ V 3+ 2 P 3 O 12 . The orthorhombic lattice constants are a = 10.488(2), b = 13.213(3), and c = 6.455(1) A with z = 4. The structure was solved with the space group Imma , composed of OPOVO chains combined with V 2 P 2 O 14 units which are formed by edge-sharing of tetrahedra and octahedra. The sodium ions are located in a tunnel in a framework similar to α-CrPO 4 .
