ReRu3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Re(1) is bonded to twelve equivalent Ru(1) atoms to form ReRu12 cuboctahedra that share corners with six equivalent Re(1)Ru12 cuboctahedra, corners with twelve equivalent Ru(1)Re4Ru8 cuboctahedra, edges with eighteen equivalent Ru(1)Re4Ru8 cuboctahedra, faces with eight equivalent Re(1)Ru12 cuboctahedra, and faces with twelve equivalent Ru(1)Re4Ru8 cuboctahedra. Ru(1) is bonded to four equivalent Re(1) and eight equivalent Ru(1) atoms to form distorted RuRe4Ru8 cuboctahedra that share corners with four equivalent Re(1)Ru12 cuboctahedra, corners with fourteen equivalent Ru(1)Re4Ru8 cuboctahedra, edges with six equivalent Re(1)Ru12 cuboctahedra, edges with twelve equivalent Ru(1)Re4Ru8 cuboctahedra, faces with four equivalent Re(1)Ru12 cuboctahedra, and faces with sixteen equivalent Ru(1)Re4Ru8 cuboctahedra.

There are six shorter (2.66 Å) and six longer (2.72 Å) Re(1)-Ru(1) bond lengths. Ru(1) is bonded to four equivalent Re(1) and eight equivalent Ru(1) atoms to form distorted RuRe4Ru8 cuboctahedra that share corners with four equivalent Re(1)Ru12 cuboctahedra, corners with fourteen equivalent Ru(1)Re4Ru8 cuboctahedra, edges with six equivalent Re(1)Ru12 cuboctahedra, edges with twelve equivalent Ru(1)Re4Ru8 cuboctahedra, faces with four equivalent Re(1)Ru12 cuboctahedra, and faces with sixteen equivalent Ru(1)Re4Ru8 cuboctahedra. There are a spread of Ru(1)-Ru(1) bond distances ranging from 2.67-2.74 Å.
