Materials Data on Tb(BRu)4 by Materials Project
Tb(RuB)4 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. Tb3+ is bonded in a 12-coordinate geometry to twelve equivalent B3- atoms. There are a spread of Tb–B bond distances ranging from 2.95–3.23 Å. 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 2.15–2.30 Å. B3- is bonded in a 6-coordinate geometry to three equivalent Tb3+, five equivalent Ru+2.25+, and one B3- atom. The B–B bond length is 1.79 Å.
