Title: Materials Data on Ba3U2(PO5)4 by Materials Project

Abstract

Ba3U2(PO5)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Ba–O bond distances ranging from 2.73–3.16 Å. In the second Ba site, Ba is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Ba–O bond distances ranging from 2.70–3.30 Å. U is bonded to seven O atoms to form distorted UO7 pentagonal bipyramids that share corners with three PO4 tetrahedra and an edgeedge with one PO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.81–2.48 Å. There are two inequivalent P sites. In the first P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with two equivalent UO7 pentagonal bipyramids and an edgeedge with one UO7 pentagonal bipyramid. There is two shorter (1.55 Å) and two longer (1.56 Å) P–O bond length. In the second P site, P is bonded to four O atoms to form PO4 tetrahedra that share a cornercorner with one UO7 pentagonal bipyramid. There are a spread of P–O bond distances rangingmore » from 1.53–1.56 Å. There are ten inequivalent O sites. In the first O site, O is bonded in a 1-coordinate geometry to one Ba, one U, and one P atom. In the second O site, O is bonded in a single-bond geometry to one Ba and one P atom. In the third O site, O is bonded in a distorted single-bond geometry to two Ba and one P atom. In the fourth O site, O is bonded in a distorted single-bond geometry to two Ba and one P atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one Ba, one U, and one P atom. In the sixth O site, O is bonded in a distorted single-bond geometry to two equivalent Ba and one U atom. In the seventh O site, O is bonded in a distorted single-bond geometry to two Ba, one U, and one P atom. In the eighth O site, O is bonded in a single-bond geometry to one U atom. In the ninth O site, O is bonded in a 1-coordinate geometry to two Ba, one U, and one P atom. In the tenth O site, O is bonded in a 1-coordinate geometry to two equivalent Ba, one U, and one P atom.« less
