Materials Data on Cu2BiPO6 by Materials Project
BiCu2PO6 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 trigonal bipyramids that share corners with two equivalent CuO5 square pyramids, corners with three equivalent PO4 tetrahedra, and an edgeedge with one CuO5 square pyramid. There are a spread of Cu–O bond distances ranging from 1.93–2.45 Å. In the second Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 square pyramids that share corners with three equivalent PO4 tetrahedra, corners with two equivalent CuO5 trigonal bipyramids, and an edgeedge with one CuO5 trigonal bipyramid. There are a spread of Cu–O bond distances ranging from 1.94–2.25 Å. Bi3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.24–2.84 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent CuO5 square pyramids and corners with three equivalent CuO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Cu2+, two equivalent Bi3+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Cu2+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cu2+, one Bi3+, and one P5+ atom. In the fourth O2- site, O2- is bonded to two Cu2+ and two equivalent Bi3+ atoms to form a mixture of distorted corner and edge-sharing OCu2Bi2 tetrahedra.
