Materials Data on CeAl2BRu2 by Materials Project
CeRu2Al2B crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ce is bonded in a distorted linear geometry to two equivalent B atoms. Both Ce–B bond lengths are 2.79 Å. Ru is bonded to four equivalent Al and two equivalent B atoms to form a mixture of edge, corner, and face-sharing RuAl4B2 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ru–Al bond lengths are 2.55 Å. Both Ru–B bond lengths are 2.10 Å. Al is bonded in a 4-coordinate geometry to four equivalent Ru atoms. B is bonded to two equivalent Ce and four equivalent Ru atoms to form corner-sharing BCe2Ru4 octahedra. The corner-sharing octahedral tilt angles are 0°.
