Materials Data on Mg(BC)2 by Materials Project
MgB2C2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. there are two inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a distorted hexagonal planar geometry to six C4- atoms. There are a spread of Mg–C bond distances ranging from 2.43–2.50 Å. In the second Mg2+ site, Mg2+ is bonded in a 6-coordinate geometry to six C4- atoms. There are a spread of Mg–C bond distances ranging from 2.26–2.51 Å. There are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three C4- atoms. There are a spread of B–C bond distances ranging from 1.56–1.60 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three C4- atoms. All B–C bond lengths are 1.58 Å. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three C4- atoms. All B–C bond lengths are 1.59 Å. There are three inequivalent C4- sites. In the first C4- site, C4- is bonded in a distorted trigonal planar geometry to four Mg2+ and three B3+ atoms. In the second C4- site, C4- is bonded in a distorted trigonal planar geometry to three Mg2+ and three B3+ atoms. In the third C4- site, C4- is bonded in a distorted trigonal planar geometry to two equivalent Mg2+ and three B3+ atoms.
