Crystal data for α ‐, β ‐ and γ ‐Ag 2 WO 4 were collected from Cu K α 1 powder diagrams, α ‐Ag 2 WO 4 is orthorhombic ( Pn 2 n ) with a = 10.820(2), b = 12.018(2) and c = 5.900(1) Å. β ‐Ag 2 WO 4 is hexagonal ( P 6 3 or P 6 3 / m ) with a = 11.0925(3) and c = 7.5424(4) Å. γ ‐Ag 2 WO 4 is cubic ( Fd 3 m , spinel type) with a = 9.352(1) Å.
