Materials Data on VRu3 by Materials Project

VRu3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. V is bonded to twelve equivalent Ru atoms to form VRu12 cuboctahedra that share corners with six equivalent VRu12 cuboctahedra, corners with twelve equivalent RuV4Ru8 cuboctahedra, edges with eighteen equivalent RuV4Ru8 cuboctahedra, faces with eight equivalent VRu12 cuboctahedra, and faces with twelve equivalent RuV4Ru8 cuboctahedra. There are six shorter (2.63 Å) and six longer (2.73 Å) V–Ru bond lengths. Ru is bonded to four equivalent V and eight equivalent Ru atoms to form distorted RuV4Ru8 cuboctahedra that share corners with four equivalent VRu12 cuboctahedra, corners with fourteen equivalent RuV4Ru8 cuboctahedra, edges with six equivalent VRu12 cuboctahedra, edges with twelve equivalent RuV4Ru8 cuboctahedra, faces with four equivalent VRu12 cuboctahedra, and faces with sixteen equivalent RuV4Ru8 cuboctahedra. There are a spread of Ru–Ru bond distances ranging from 2.67–2.79 Å.

Materials Data on VRu3 by Materials Project

VRu3 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. V is bonded to six equivalent V and six equivalent Ru atoms to form distorted VV6Ru6 cuboctahedra that share corners with six equivalent VV6Ru6 cuboctahedra, corners with twelve equivalent RuRu12 cuboctahedra, edges with six equivalent VV6Ru6 cuboctahedra, edges with twelve equivalent RuV3Ru9 cuboctahedra, faces with six equivalent VV6Ru6 cuboctahedra, and faces with fourteen RuRu12 cuboctahedra. All V–V bond lengths are 2.73 Å. All V–Ru bond lengths are 2.67 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded to twelve Ru atoms to form RuRu12 cuboctahedra that share corners with six equivalent RuRu12 cuboctahedra, corners with twelve equivalent VV6Ru6 cuboctahedra, edges with eighteen RuRu12 cuboctahedra, faces with two equivalent VV6Ru6 cuboctahedra, and faces with eighteen RuRu12 cuboctahedra. There are six shorter (2.68 Å) and six longer (2.73 Å) Ru–Ru bond lengths. In the second Ru site, Ru is bonded to three equivalent V and nine Ru atoms to form distorted RuV3Ru9 cuboctahedra that share corners with eighteen equivalent RuV3Ru9 cuboctahedra, edges with six equivalent VV6Ru6 cuboctahedra, edges with twelve RuRu12 cuboctahedra, faces with six equivalent VV6Ru6 cuboctahedra, and faces with fourteen RuRu12 cuboctahedra. All Ru–Ru bond lengths are 2.73 Å.
