Materials Data on CaU3(CO10)2 by Materials Project
Abstract
CaU3(CO10)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ca is bonded to seven O atoms to form distorted CaO7 pentagonal bipyramids that share a cornercorner with one UO8 hexagonal bipyramid and a cornercorner with one UO7 pentagonal bipyramid. There are a spread of Ca–O bond distances ranging from 2.25–2.57 Å. There are three inequivalent U sites. In the first U site, U is bonded to eight O atoms to form distorted UO8 hexagonal bipyramids that share a cornercorner with one CaO7 pentagonal bipyramid and edges with four UO7 pentagonal bipyramids. There are a spread of U–O bond distances ranging from 1.80–2.55 Å. In the second U site, U is bonded to seven O atoms to form distorted UO7 pentagonal bipyramids that share a cornercorner with one CaO7 pentagonal bipyramid, edges with two equivalent UO8 hexagonal bipyramids, and an edgeedge with one UO7 pentagonal bipyramid. There are a spread of U–O bond distances ranging from 1.81–2.52 Å. In the third U site, U is bonded to seven O atoms to form distorted UO7 pentagonal bipyramids that share edges with two equivalent UO8 hexagonal bipyramids and an edgeedge with one UO7 pentagonal bipyramid.
