Materials Data on Th2Sc(B2C)3 by Materials Project
ScTh2(B2C)3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional and consists of one scandium molecule and one Th2(B2C)3 framework. In the Th2(B2C)3 framework, Th4+ is bonded to six equivalent C+3.67- atoms to form a mixture of distorted corner, edge, and face-sharing ThC6 pentagonal pyramids. All Th–C bond lengths are 2.62 Å. B is bonded in a distorted single-bond geometry to one C+3.67- atom. The B–C bond length is 1.51 Å. C+3.67- is bonded in a distorted linear geometry to four equivalent Th4+ and two equivalent B atoms.
