Materials Data on GaAg(SO4)2 by Materials Project
AgGa(SO4)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ag1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are two shorter (2.56 Å) and four longer (2.68 Å) Ag–O bond lengths. Ga3+ is bonded to six O2- atoms to form GaO6 octahedra that share corners with six equivalent SO4 tetrahedra. There is two shorter (1.96 Å) and four longer (2.00 Å) Ga–O bond length. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three equivalent GaO6 octahedra. The corner-sharing octahedra tilt angles range from 38–46°. There are a spread of S–O bond distances ranging from 1.45–1.51 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Ag1+ and one S6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ag1+, one Ga3+, and one S6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Ga3+ and one S6+ atom.
