Materials Data on BaCa(CO3)2 by Materials Project
BaCa(CO3)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.72–3.31 Å. Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.72 Å. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.28 Å) and two longer (1.31 Å) C–O bond length. There are six 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 1-coordinate geometry to two equivalent Ba2+, one Ca2+, and one C4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ba2+, one Ca2+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ba2+, one Ca2+, and one C4+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Ba2+, two equivalent Ca2+, and one C4+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Ba2+, two equivalent Ca2+, and one C4+ atom.
