Magnetic susceptibility measurements at various temperatures and magnetic flux densities and diffuse reflectance spectra of carefully prepared and handled silver permanganate (AgMnO//4) are reported. The key value for X//M(AgMnO//4) is (2. 75 plus or minus 0. 1) multiplied by 10** minus **1**0 m**3 mol** minus **1 at 300K and 1. 3T. The results confirm the model of a multicentre interaction suggested in the literature. In addition, the results clearly point at the importance of the preparation and storage of the sample under well-defined and reproducible conditions since the magnetic properties change significantly with higher temperatures tending to an increased paramagnetic behaviour.
