The structure described by AgGaO2 crystallizes in the orthorhombic Pna2_1 space group. Ag(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form AgO4 tetrahedra that share corners with four equivalent Ag(1)O4 tetrahedra and corners with eight equivalent Ga(1)O4 tetrahedra. Ga(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form GaO4 tetrahedra that share corners with four equivalent Ga(1)O4 tetrahedra and corners with eight equivalent Ag(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ag(1) and two equivalent Ga(1) atoms to form distorted corner-sharing OGa2Ag2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Ag(1) and two equivalent Ga(1) atoms to form distorted corner-sharing OGa2Ag2 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
