Materials Data on BaCO3 by Materials Project

Abstract

BaCO3 is Potassium chlorate structured and crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.72–3.08 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.30 Å) and one longer (1.31 Å) C–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one C4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one C4+ atom.
