Materials Data on CaB3O10 by Materials Project
CaB3O10 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one CaB3O10 sheet oriented in the (1, 0, 0) direction. Ca is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Ca–O bond distances ranging from 2.21–3.09 Å. There are three inequivalent B sites. In the first B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.34–1.39 Å. In the second B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.35–1.40 Å. In the third B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.29–1.53 Å. There are ten inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to two B atoms. In the second O site, O is bonded in a bent 150 degrees geometry to two B atoms. In the third O site, O is bonded in a 3-coordinate geometry to two equivalent Ca and one O atom. The O–O bond length is 1.34 Å. In the fourth O site, O is bonded in a single-bond geometry to one B atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one Ca and one B atom. In the sixth O site, O is bonded in a distorted single-bond geometry to one Ca and one B atom. In the seventh O site, O is bonded in a distorted single-bond geometry to one Ca, one B, and one O atom. In the eighth O site, O is bonded in a distorted bent 120 degrees geometry to one Ca and one B atom. In the ninth O site, O is bonded in a distorted single-bond geometry to one Ca and one O atom. The O–O bond length is 1.22 Å. In the tenth O site, O is bonded in a single-bond geometry to one Ca atom.
