Abstract—The binuclear osmium complex Os₃S₇SeCl₈ was prepared by the reaction of cluster chalcogen chlo-
ride K₆Os₂S₂O₆(CN)₈ with an aqueous KCN solution. In the complex, the distance between the osmium atoms
is 2.85 Å, and they are linked by - bridges with the OsSOs angle of 75.9. The osmium coordination
number is 6. In the reaction with CN^– ligands under study, the individual fragments of the structure are retained;
however, the trinuclear cluster skeleton of Os₃S₇SeCl₈ is destroyed.
