The compound described by Pr3Ru4Ge13 crystallizes in the cubic Pm-3n space group. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Ru(1) and twelve equivalent Ge(2) atoms. Ru(1) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 2-coordinate geometry to three equivalent Pr(1), two equivalent Ru(1), and one Ge(1) atom. In the second Ge site, Ge(1) is bonded in a cuboctahedral geometry to twelve equivalent Ge(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
