Ru3Cl is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to four equivalent Ru(2) and four equivalent Cl(1) atoms to form distorted RuRu4Cl4 tetrahedra that share corners with eight equivalent Ru(2)Ru8Cl4 cuboctahedra, corners with eight equivalent Cl(1)Ru12 cuboctahedra, corners with eight equivalent Ru(1)Ru4Cl4 tetrahedra, edges with four equivalent Ru(2)Ru8Cl4 cuboctahedra, edges with four equivalent Cl(1)Ru12 cuboctahedra, edges with twelve equivalent Ru(1)Ru4Cl4 tetrahedra, and faces with six equivalent Ru(1)Ru4Cl4 tetrahedra. In the second Ru site, Ru(2) is bonded to eight equivalent Ru(1) and four equivalent Cl(1) atoms to form RuRu8Cl4 cuboctahedra that share corners with four equivalent Ru(2)Ru8Cl4 cuboctahedra, corners with eight equivalent Cl(1)Ru12 cuboctahedra, corners with sixteen equivalent Ru(1)Ru4Cl4 tetrahedra, edges with eight equivalent Ru(2)Ru8Cl4 cuboctahedra, edges with eight equivalent Ru(1)Ru4Cl4 tetrahedra, faces with four equivalent Ru(2)Ru8Cl4 cuboctahedra, and faces with six equivalent Cl(1)Ru12 cuboctahedra. Cl(1) is bonded to four equivalent Ru(2) and eight equivalent Ru(1) atoms to form distorted ClRu12 cuboctahedra that share corners with four equivalent Cl(1)Ru12 cuboctahedra, corners with eight equivalent Ru(2)Ru8Cl4 cuboctahedra, corners with sixteen equivalent Ru(1)Ru4Cl4 tetrahedra, edges with eight equivalent Cl(1)Ru12 cuboctahedra, edges with eight equivalent Ru(1)Ru4Cl4 tetrahedra, faces with four equivalent Cl(1)Ru12 cuboctahedra, and faces with six equivalent Ru(2)Ru8Cl4 cuboctahedra.
