Materials Data on Mg(B6C)2 by Materials Project

B12C2Mg crystallizes in the orthorhombic Imma space group. The structure is zero-dimensional and consists of twenty-four boron, metallic molecules and four Mg(B3C)2 clusters. In each Mg(B3C)2 cluster, Mg2+ is bonded in a 2-coordinate geometry to two equivalent C4- atoms. Both Mg–C bond lengths are 2.29 Å. There are two inequivalent B+0.50+ sites. In the first B+0.50+ site, B+0.50+ is bonded in a single-bond geometry to one C4- atom. The B–C bond length is 1.66 Å. In the second B+0.50+ site, B+0.50+ is bonded in a single-bond geometry to one C4- atom. The B–C bond length is 1.65 Å. C4- is bonded in a 5-coordinate geometry to one Mg2+, three B+0.50+, and one C4- atom. The C–C bond length is 1.72 Å.
