Materials Data on BaCu2P2H2O9 by Materials Project
BaCu2(PO4)2(H2O) crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.74–3.27 Å. 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 a cornercorner with one CuO5 square pyramid, corners with four PO4 tetrahedra, and an edgeedge with one CuO5 square pyramid. There are a spread of Cu–O bond distances ranging from 1.93–2.54 Å. In the second Cu2+ site, Cu2+ is bonded to five O2- atoms to form CuO5 square pyramids that share corners with four PO4 tetrahedra, a cornercorner with one CuO5 trigonal bipyramid, and an edgeedge with one CuO5 trigonal bipyramid. There are a spread of Cu–O bond distances ranging from 1.94–2.29 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 two equivalent CuO5 square pyramids and corners with two equivalent CuO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CuO5 square pyramids and corners with two equivalent CuO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Ba2+, one Cu2+, and one P5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to two equivalent Ba2+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ba2+, two Cu2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ba2+, two Cu2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to two Cu2+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Cu2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one Ba2+, one Cu2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Cu2+, and one P5+ atom.
