Materials Data on Pr(BRu)4 by Materials Project

Pr(RuB)4 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. Pr3+ is bonded to twelve equivalent B3- atoms to form distorted PrB12 cuboctahedra that share corners with twelve equivalent RuB5 trigonal bipyramids, edges with twelve equivalent PrB12 cuboctahedra, edges with four equivalent RuB5 trigonal bipyramids, and faces with twelve equivalent RuB5 trigonal bipyramids. There are a spread of Pr–B bond distances ranging from 3.01–3.23 Å. Ru+2.25+ is bonded to five equivalent B3- atoms to form distorted RuB5 trigonal bipyramids that share corners with three equivalent PrB12 cuboctahedra, corners with eight equivalent RuB5 trigonal bipyramids, an edgeedge with one PrB12 cuboctahedra, edges with six equivalent RuB5 trigonal bipyramids, and faces with three equivalent PrB12 cuboctahedra. There are a spread of Ru–B bond distances ranging from 2.16–2.32 Å. B3- is bonded in a 6-coordinate geometry to three equivalent Pr3+, five equivalent Ru+2.25+, and one B3- atom. The B–B bond length is 1.81 Å.
