Ag3SI is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Ag(1) is bonded in a linear geometry to two equivalent S(1) and four equivalent I(1) atoms. S(1) is bonded to six equivalent Ag(1) atoms to form SAg6 octahedra that share corners with six equivalent S(1)Ag6 octahedra and faces with eight equivalent I(1)Ag12 cuboctahedra. The corner-sharing octahedra are not tilted. I(1) is bonded to twelve equivalent Ag(1) atoms to form IAg12 cuboctahedra that share corners with twelve equivalent I(1)Ag12 cuboctahedra, faces with six equivalent I(1)Ag12 cuboctahedra, and faces with eight equivalent S(1)Ag6 octahedra.
Ag3SI is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Ag(1) is bonded in a linear geometry to two equivalent S(1) and four equivalent I(1) atoms. Both Ag(1)-S(1) bond lengths are 2.50 Å. All Ag(1)-I(1) bond lengths are 3.54 Å. S(1) is bonded to six equivalent Ag(1) atoms to form SAg6 octahedra that share corners with six equivalent S(1)Ag6 octahedra and faces with eight equivalent I(1)Ag12 cuboctahedra. The corner-sharing octahedra are not tilted. I(1) is bonded to twelve equivalent Ag(1) atoms to form IAg12 cuboctahedra that share corners with twelve equivalent I(1)Ag12 cuboctahedra, faces with six equivalent I(1)Ag12 cuboctahedra, and faces with eight equivalent S(1)Ag6 octahedra.
