Re3Ru is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to eight Re(1,1) and four equivalent Ru(1) atoms to form distorted ReRe8Ru4 cuboctahedra that share corners with four equivalent Ru(1)Re12 cuboctahedra; corners with fourteen Re(1,1)Re8Ru4 cuboctahedra; edges with six equivalent Ru(1)Re12 cuboctahedra; edges with twelve Re(1,1)Re8Ru4 cuboctahedra; faces with four equivalent Ru(1)Re12 cuboctahedra; and faces with sixteen Re(1,1)Re8Ru4 cuboctahedra. In the second Re site, Re(1) is bonded to eight Re(1,1) and four equivalent Ru(1) atoms to form distorted ReRe8Ru4 cuboctahedra that share corners with four equivalent Ru(1)Re12 cuboctahedra; corners with fourteen Re(1,1)Re8Ru4 cuboctahedra; edges with six equivalent Ru(1)Re12 cuboctahedra; edges with twelve Re(1,1)Re8Ru4 cuboctahedra; faces with four equivalent Ru(1)Re12 cuboctahedra; and faces with sixteen Re(1,1)Re8Ru4 cuboctahedra. Ru(1) is bonded to twelve Re(1,1) atoms to form RuRe12 cuboctahedra that share corners with six equivalent Ru(1)Re12 cuboctahedra; corners with twelve Re(1,1)Re8Ru4 cuboctahedra; edges with eighteen Re(1,1)Re8Ru4 cuboctahedra; faces with eight equivalent Ru(1)Re12 cuboctahedra; and faces with twelve Re(1,1)Re8Ru4 cuboctahedra.

There are a spread of Re(1)-Re(1,1) bond distances ranging from 2.70-2.80 Å. There are two shorter (2.73 Å) and two longer (2.76 Å) Re(1)-Ru(1) bond lengths.
