Y3Ru4Ge13 crystallizes in the cubic Pm-3n space group. Y(1) is bonded in a 16-coordinate geometry to four equivalent Ru(1) and twelve equivalent Ge(1) atoms. Ru(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a cuboctahedral geometry to twelve equivalent Ge(1) atoms. In the second Ge site, Ge(1) is bonded in a 6-coordinate geometry to three equivalent Y(1), two equivalent Ru(1), one Ge(1), and one Ge(2) atom.
