Materials Data on NbCu(PO4)2 by Materials Project
Abstract
NbCu(PO4)2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Nb5+ is bonded to six O2- atoms to form NbO6 pentagonal pyramids that share corners with four PO4 tetrahedra and an edgeedge with one PO4 tetrahedra. There are a spread of Nb–O bond distances ranging from 1.99–2.07 Å. Cu1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.96–2.63 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent NbO6 pentagonal pyramids. There is one shorter (1.51 Å) and three longer (1.57 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NbO6 pentagonal pyramid and an edgeedge with one NbO6 pentagonal pyramid. There are a spread of P–O bond distances ranging from 1.49–1.59 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Nb5+ and one P5+ atom. In the second O2- site, O2- is bonded inmore »
