Exposure of [MnIII6CrIII]3+ single-molecule magnets to soft X-rays: The effect of the counterions on radiation stability

► [MnIII6CrIII]3+ single-molecule magnets adsorbed on gold are investigated. ► The oxidation state of the MnIII constituents changes under X-ray exposure. ► The change is monitored by Mn-L3-edge XAS. ► Choice of anions strongly influences radiation stability of the SMM. ► No influence of the sample morphology on radiation stability could be observed.
