Materials Data on CaPH5(WO2)2 by Materials Project
Abstract
CaPH5(WO2)2 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Ca2+ is bonded in a 7-coordinate geometry to one H1+ and six O2- atoms. The Ca–H bond length is 2.41 Å. There are a spread of Ca–O bond distances ranging from 2.27–2.86 Å. There are two inequivalent W2+ sites. In the first W2+ site, W2+ is bonded to four H1+ and one O2- atom to form WH4O trigonal bipyramids that share a cornercorner with one PO4 tetrahedra, corners with three equivalent WH4 tetrahedra, and corners with two equivalent WH4O trigonal bipyramids. There are a spread of W–H bond distances ranging from 1.81–2.03 Å. The W–O bond length is 2.20 Å. In the second W2+ site, W2+ is bonded to four H1+ atoms to form distorted WH4 tetrahedra that share corners with two equivalent WH4 tetrahedra and corners with three equivalent WH4O trigonal bipyramids. There are a spread of W–H bond distances ranging from 1.88–2.20 Å. P3- is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one WH4O trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.52–1.62 Å. There are five inequivalent H1+ sites. In the first H1+ site,more »

In the third H1+ site, H1+ is bonded in a water-like geometry to one Ca2+ and one W2+ atom. In the fourth H1+ site, H1+ is bonded in a bent 120 degrees geometry to two equivalent W2+ atoms. In the fifth H1+ site, H1+ is bonded in a bent 150 degrees geometry to two W2+ atoms. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ca2+ and one P3- atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ca2+, one W2+, and one P3- atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and one P3- atom.
