Materials Data on Eu(BRu)4 by Materials Project
Eu(RuB)4 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. Eu2+ is bonded in a 12-coordinate geometry to twelve equivalent B3- atoms. There are a spread of Eu–B bond distances ranging from 2.96–3.25 Å. Ru+2.50+ is bonded to five equivalent B3- atoms to form a mixture of distorted edge and corner-sharing RuB5 trigonal bipyramids. There are a spread of Ru–B bond distances ranging from 2.15–2.31 Å. B3- is bonded in a 6-coordinate geometry to three equivalent Eu2+, five equivalent Ru+2.50+, and one B3- atom. The B–B bond length is 1.80 Å.
