YAgO2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Y3+ is bonded to six equivalent O2- atoms to form edge-sharing YO6 octahedra. All Y–O bond lengths are 2.30 Å. Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.09 Å. O2- is bonded to three equivalent Y3+ and one Ag1+ atom to form a mixture of edge and corner-sharing OY3Ag tetrahedra.
YAgO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Y3+ is bonded to twelve equivalent O2- atoms to form YO12 cuboctahedra that share corners with twelve equivalent YO12 cuboctahedra, faces with six equivalent YO12 cuboctahedra, and faces with eight equivalent AgO6 octahedra. All Y–O bond lengths are 2.87 Å. Ag3+ is bonded to six equivalent O2- atoms to form AgO6 octahedra that share corners with six equivalent AgO6 octahedra and faces with eight equivalent YO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ag–O bond lengths are 2.03 Å. O2- is bonded in a distorted linear geometry to four equivalent Y3+ and two equivalent Ag3+ atoms.
