The material structure described by Er(RuB)4 crystallizes in the tetragonal I4_1/acd space group. Er(1) is bonded in a 24-coordinate geometry to twelve equivalent Ru(1) and twelve equivalent B(1) atoms. Ru(1) is bonded in a 5-coordinate geometry to three equivalent Er(1) and five equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Er(1), five equivalent Ru(1), and one B(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
