The structure described by La5Ru2 crystallizes in the monoclinic C2/c space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to three equivalent Ru(1) atoms. In the second La site, La(3) is bonded to four equivalent Ru(1) atoms to form distorted edge-sharing LaRu4 trigonal pyramids. In the third La site, La(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. Ru(1) is bonded in a 8-coordinate geometry to two equivalent La(3), three equivalent La(1), and three equivalent La(2) atoms. is represented by the CIF card [CIF]
