Materials Data on Y(CO3)2 by Materials Project

Abstract

Y(CO3)2 crystallizes in the orthorhombic C222_1 space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Y–O bond distances ranging from 2.38–2.50 Å. In the second Y site, Y is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Y–O bond distances ranging from 2.37–2.46 Å. There are two inequivalent C sites. In the first C site, C is bonded in a distorted bent 120 degrees geometry to two O atoms. Both C–O bond lengths are 1.25 Å. In the second C site, C is bonded in a trigonal planar geometry to three O atoms. There is two shorter (1.29 Å) and one longer (1.30 Å) C–O bond length. There are seven inequivalent O sites. In the first O site, O is bonded in a 1-coordinate geometry to two Y and one C atom. In the second O site, O is bonded in a distorted T-shaped geometry to two Y and one C atom. In the third O site, O is bonded in a 1-coordinate geometry to two Y and one C atom. In the fourth O site, O is bonded in a single-bond geometry to one Y atom. In the fifth O site, O is bonded in a single-bond geometry to one Y atom. In the sixth O site, O is bonded in a bent 120 degrees geometry to one Y and one C atom. In the seventh O site, O is bonded in a bent 120 degrees geometry to one Y and one C atom.
