Popis:	Ru3+ and Ru2+ ions are substitutionally incorporated into melt‐grown crystals of AgBr and AgCl. The d5 trivalent ion predominates in samples prepared in oxidizing environments, such as Br2 and Cl2, and it has been the subject of a detailed magnetic resonance study. It is distributed between four structurally inequivalent lattice sites in both salts. These sites are distinguished by the arrangement of charge‐compensating silver‐ion vacancies in the two closest cation subshells. Reasonable dopant‐vacancy configurations have been deduced from the EPR data.
