There are a spread of Ru–Ru bond distances ranging from 2.61–2.67 Å. There are one shorter (2.62 Å) and one longer (2.63 Å) Ru–Ni bond lengths. In the second Ru site, Ru is bonded to six Ho, three Ru, and three Ni atoms to form RuHo6Ni3Ru3 cuboctahedra that share corners with six NiHo6Ni2Ru4 cuboctahedra, corners with twelve RuHo6Ni2Ru4 cuboctahedra, edges with six equivalent RuHo6Ni3Ru3 cuboctahedra, faces with nine RuHo6Ni2Ru4 cuboctahedra, and faces with nine NiHo6Ni2Ru4 cuboctahedra. There are one shorter (2.54 Å) and one longer (2.61 Å) Ru–Ru bond lengths. There are two shorter (2.62 Å) and one longer (2.66 Å) Ru–Ni bond lengths. In the third Ru site, Ru is bonded to six equivalent Ho, four Ru, and two equivalent Ni atoms to form RuHo6Ni2Ru4 cuboctahedra that share corners with four equivalent NiHo6Ru6 cuboctahedra, corners with fourteen RuHo6Ni2Ru4 cuboctahedra, edges with six equivalent RuHo6Ni2Ru4 cuboctahedra, faces with six equivalent NiHo6Ru6 cuboctahedra, and faces with twelve RuHo6Ni2Ru4 cuboctahedra. Both Ru–Ru bond lengths are 2.60 Å. Both Ru–Ni bond lengths are 2.63 Å. In the fourth Ru site, Ru is bonded to six Ho, two equivalent Ru, and four Ni atoms to form RuHo6Ni4Ru2 cuboctahedra that share corners with four equivalent NiHo6Ru6 cuboctahedra, corners with fourteen RuHo6Ni2Ru4 cuboctahedra, edges with six RuHo6Ni2Ru4 cuboctahedra, faces with eight RuHo6Ni2Ru4 cuboctahedra, and faces with ten NiHo6Ni2Ru4 cuboctahedra. There are two shorter (2.62 Å) and two longer (2.63 Å) Ru–Ni bond lengths. In the fifth Ru site, Ru is bonded to six Ho, four Ru, and two equivalent Ni atoms to form RuHo6Ni2Ru4 cuboctahedra that share corners with six NiHo6Ni2Ru4 cuboctahedra, corners with twelve RuHo6Ni2Ru4 cuboctahedra, edges with six RuHo6Ni4Ru2 cuboctahedra, faces with seven NiHo6Ni2Ru4 cuboctahedra, and faces with eleven RuHo6Ni2Ru4 cuboctahedra. There are one shorter (2.63 Å) and one longer (2.64 Å) Ru–Ni bond lengths. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded to six Ho, four Ru, and two equivalent Ni atoms to form NiHo6Ni2Ru4 cuboctahedra that share corners with six NiHo6Ni2Ru4 cuboctahedra, corners with twelve RuHo6Ni2Ru4 cuboctahedra, edges with six NiHo6Ni2Ru4 cuboctahedra, faces with four equivalent NiHo6Ni2Ru4 cuboctahedra, and faces with fourteen RuHo6Ni2Ru4 cuboctahedra. Both Ni–Ni bond lengths are 2.62 Å. In the second Ni site, Ni is bonded to six Ho and six Ru atoms to form NiHo6Ru6 cuboctahedra that share corners with eight NiHo6Ni2Ru4 cuboctahedra, corners with ten RuHo6Ni2Ru4 cuboctahedra, edges with six NiHo6Ni2Ru4 cuboctahedra, a faceface with one NiHo6Ni2Ru4 cuboctahedra, and faces with seventeen RuHo6Ni2Ru4 cuboctahedra. In the third Ni site, Ni is bonded to six Ho, four Ru, and two equivalent Ni atoms to form NiHo6Ni2Ru4 cuboctahedra that share corners with eight NiHo6Ru6 cuboctahedra, corners with ten RuHo6Ni2Ru4 cuboctahedra, edges with two equivalent NiHo6Ni2Ru4 cuboctahedra, edges with four equivalent RuHo6Ni2Ru4 cuboctahedra, faces with six NiHo6Ni2Ru4 cuboctahedra, and faces with twelve RuHo6Ni3Ru3 cuboctahedra.
