Materials Data on NaNi4(P2O11)2 by Materials Project
Abstract
NaNi4(PO5)4O2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional and consists of two oxygen molecules and one NaNi4(PO5)4 framework. In the NaNi4(PO5)4 framework, Na is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Na–O bond distances ranging from 2.29–2.99 Å. There are four inequivalent Ni sites. In the first Ni site, Ni is bonded to five O atoms to form NiO5 trigonal bipyramids that share corners with two NiO5 square pyramids, corners with four PO4 tetrahedra, and an edgeedge with one NiO5 square pyramid. There are a spread of Ni–O bond distances ranging from 1.92–2.06 Å. In the second Ni site, Ni is bonded to five O atoms to form NiO5 square pyramids that share a cornercorner with one NiO5 square pyramid, corners with four PO4 tetrahedra, a cornercorner with one NiO5 trigonal bipyramid, and an edgeedge with one NiO5 square pyramid. There are a spread of Ni–O bond distances ranging from 1.91–2.05 Å. In the third Ni site, Ni is bonded to five O atoms to form NiO5 square pyramids that share corners with two NiO5 square pyramids, corners with four PO4 tetrahedra, and an edgeedge with one NiO5 trigonalmore »

In the NaNi4(PO5)4 framework, Na is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Na–O bond distances ranging from 2.29–2.99 Å. There are four inequivalent Ni sites.
