Materials Data on Na2TePO11 by Materials Project
Abstract
Na2PTeO11 crystallizes in the monoclinic P2_1 space group. The structure is two-dimensional and consists of two Na2PTeO11 sheets oriented in the (0, 1, 0) direction. there are two inequivalent Na sites. In the first Na site, Na is bonded to seven O atoms to form distorted NaO7 hexagonal pyramids that share edges with three equivalent TeO6 octahedra and a faceface with one NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.37–2.52 Å. In the second Na site, Na is bonded to six O atoms to form distorted NaO6 octahedra that share corners with three equivalent TeO6 octahedra, corners with three equivalent PO4 tetrahedra, and a faceface with one NaO7 hexagonal pyramid. The corner-sharing octahedra tilt angles range from 23–25°. There are a spread of Na–O bond distances ranging from 2.36–2.65 Å. P is bonded to four O atoms to form PO4 tetrahedra that share corners with three equivalent NaO6 octahedra. The corner-sharing octahedra tilt angles range from 43–51°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. Te is bonded to six O atoms to form TeO6 octahedra that share corners with three equivalent NaO6 octahedra and edges with three equivalent NaO7 hexagonalmore »

In the seventh O site, O is bonded in a bent 120 degrees geometry to one Na and one Te atom. In the eighth O site, O is bonded in a water-like geometry to one Na and one Te atom. In the ninth O site, O is bonded in a bent 120 degrees geometry to one Na and one Te atom. In the tenth O site, O is bonded in a single-bond geometry to one P atom. In the eleventh O site, O is bonded in a single-bond geometry to one Na atom.},
