The compound described by Be3Ru2 crystallizes in the cubic Ia-3 space group. Be(1) is bonded in a 8-coordinate geometry to three equivalent Be(1), one Ru(2), and four equivalent Ru(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 4-coordinate geometry to eight equivalent Be(1) and two equivalent Ru(2) atoms. In the second Ru site, Ru(2) is bonded to six equivalent Be(1) and six equivalent Ru(1) atoms to form distorted corner-sharing RuBe6Ru6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
