The structure described by YRu2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded in a 12-coordinate geometry to three equivalent Ru(2) and nine equivalent Ru(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded to six equivalent Y(1) and six equivalent Ru(1) atoms to form a mixture of corner, edge, and face-sharing RuY6Ru6 cuboctahedra. In the second Ru site, Ru(1) is bonded to six equivalent Y(1), two equivalent Ru(2), and four equivalent Ru(1) atoms to form a mixture of corner, edge, and face-sharing RuY6Ru6 cuboctahedra. is represented by the CIF file [CIF]
