Re3Ru is beta-derived structured and crystallizes in the orthorhombic Imm2 space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to two equivalent Re(1), six equivalent Re(2), and four equivalent Ru(1) atoms to form ReRe8Ru4 cuboctahedra that share corners with four equivalent Ru(1)Re10Ru2 cuboctahedra, corners with fourteen equivalent Re(1)Re8Ru4 cuboctahedra, edges with two equivalent Re(1)Re8Ru4 cuboctahedra, edges with four equivalent Ru(1)Re10Ru2 cuboctahedra, edges with twelve equivalent Re(2)Re9Ru3 cuboctahedra, faces with two equivalent Re(1)Re8Ru4 cuboctahedra, faces with six equivalent Ru(1)Re10Ru2 cuboctahedra, and faces with twelve equivalent Re(2)Re9Ru3 cuboctahedra. In the second Re site, Re(2) is bonded to three equivalent Re(1), six equivalent Re(2), and three equivalent Ru(1) atoms to form distorted ReRe9Ru3 cuboctahedra that share corners with eighteen equivalent Re(2)Re9Ru3 cuboctahedra, edges with six equivalent Re(1)Re8Ru4 cuboctahedra, edges with six equivalent Re(2)Re9Ru3 cuboctahedra, edges with six equivalent Ru(1)Re10Ru2 cuboctahedra, faces with six equivalent Re(1)Re8Ru4 cuboctahedra, faces with six equivalent Ru(1)Re10Ru2 cuboctahedra, and faces with eight equivalent Re(2)Re9Ru3 cuboctahedra. Ru(1) is bonded to four equivalent Re(1), six equivalent Re(2), and two equivalent Ru(1) atoms to form RuRe10Ru2 cuboctahedra that share corners with four equivalent Re(1)Re8Ru4 cuboctahedra, corners with fourteen equivalent Ru(1)Re10Ru2 cuboctahedra, edges with two equivalent Ru(1)Re10Ru2 cuboctahedra, edges with four equivalent Re(1)Re8Ru4 cuboctahedra, edges with twelve equivalent Re(2)Re9Ru3 cuboctahedra, faces with two equivalent Ru(1)Re10Ru2 cuboctahedra, faces with six equivalent Re(1)Re8Ru4 cuboctahedra, and faces with twelve equivalent Re(2)Re9Ru3 cuboctahedra.
