CaRu3Ag is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Ca(1) is bonded to twelve equivalent Ru(1) atoms to form distorted CaRu12 cuboctahedra that share corners with twelve equivalent Ca(1)Ru12 cuboctahedra, faces with six equivalent Ca(1)Ru12 cuboctahedra, and faces with eight equivalent Ag(1)Ru6 octahedra. There are a spread of Ca(1)-Ru(1) bond distances ranging from 3.11-3.81 Å. Ru(1) is bonded in a 1-coordinate geometry to four equivalent Ca(1) and two equivalent Ag(1) atoms. There is one shorter (2.20 Å) and one longer (2.70 Å) Ru(1)-Ag(1) bond length. Ag(1) is bonded to six equivalent Ru(1) atoms to form AgRu6 octahedra that share corners with six equivalent Ag(1)Ru6 octahedra and faces with eight equivalent Ca(1)Ru12 cuboctahedra. The corner-sharing octahedra are not tilted.
