Abstract

(AgI)_1-x(Ag₂MoO₄)_x glasses and crystals have been studied by X-ray absorption spectroscopy at the Mo K-edge. All the measured samples contain isolated [MoO₄] tetrahedra with R(Mo-O) = 1.785±0.008 angstroms and mean square relative displacement (MSRD) σ² = 0.0043±0.0013 angstrom², which are unchanged upon insertion of AgI. The glasses have a quite similar environment around molybdenum, which resembles that of the crystal (AgI)_x(Ag₂MoO₄)_x with x = 0.33. The presence of AgI modifies the local environment around molybdenum already in the second coordination shell.
