Materials Data on Yb(BRu)2 by Materials Project

Yb(RuB)2 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. Yb2+ is bonded in a square co-planar geometry to four equivalent B3- atoms. There are two shorter (2.67 Å) and two longer (2.68 Å) Yb–B bond lengths. Ru2+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent B3- atoms. There are two shorter (2.03 Å) and two longer (2.28 Å) Ru–B bond lengths. B3- is bonded to two equivalent Yb2+, four equivalent Ru2+, and one B3- atom to form a mixture of distorted edge, corner, and face-sharing BYb2BRu4 hexagonal pyramids. The B–B bond length is 1.77 Å.
