Abstract

NbNi3(PO4)4 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. Nb5+ is bonded to six O2- atoms to form distorted NbO6 pentagonal pyramids that share corners with four equivalent NiO6 octahedra, corners with four PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra.
