Materials Data on Ag3Ru by Materials Project
RuAg3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ru is bonded to twelve equivalent Ag atoms to form RuAg12 cuboctahedra that share corners with six equivalent RuAg12 cuboctahedra, corners with twelve equivalent AgAg8Ru4 cuboctahedra, edges with eighteen equivalent AgAg8Ru4 cuboctahedra, faces with eight equivalent RuAg12 cuboctahedra, and faces with twelve equivalent AgAg8Ru4 cuboctahedra. There are six shorter (2.88 Å) and six longer (2.91 Å) Ru–Ag bond lengths. Ag is bonded to four equivalent Ru and eight equivalent Ag atoms to form AgAg8Ru4 cuboctahedra that share corners with four equivalent RuAg12 cuboctahedra, corners with fourteen equivalent AgAg8Ru4 cuboctahedra, edges with six equivalent RuAg12 cuboctahedra, edges with twelve equivalent AgAg8Ru4 cuboctahedra, faces with four equivalent RuAg12 cuboctahedra, and faces with sixteen equivalent AgAg8Ru4 cuboctahedra. There are a spread of Ag–Ag bond distances ranging from 2.88–2.94 Å.
