As a basis to understand essential variations of optical properties, the layered compound K2Na[Ag(CN)2]3 was investigated by means of high-resolution powder neutron diffraction in the temperature range from 9 K to 300 K. Sample oscillation during the measurements reduced preferred orientation problems significantly. As a function of temperature the chemical structure corresponding to space group C 2/m is found, by means of profile analysis and rigid-body constraints, to change continuously with small reorientations of two approximately linear [N-C-Ag-C-N]- units [mainly the angle |θ2|: 26.1°, 26.5° at 9 K, 300 K, respectively for Ag(2)], resulting in an anomalous increase of the c-lattice parameter with decreasing temperature.
