Materials Data on Sc(BRu)4 by Materials Project
ScRu4B4 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. Sc3+ is bonded in a 8-coordinate geometry to eight equivalent B3- atoms. There are four shorter (2.91 Å) and four longer (2.99 Å) Sc–B bond lengths. Ru+2.25+ is bonded to five equivalent B3- atoms to form a mixture of distorted corner and edge-sharing RuB5 trigonal bipyramids. There are a spread of Ru–B bond distances ranging from 2.13–2.27 Å. B3- is bonded in a 6-coordinate geometry to two equivalent Sc3+, five equivalent Ru+2.25+, and one B3- atom. The B–B bond length is 1.77 Å.
