Dehalogenation of[1,2-Ph2-3,3-(PPh3)2-3-Cl-closo/pseudocloso-3,1,2-RuC2B9H9]− affords, in addition to the unusual “symbiotic”** cluster [(1,2-Ph2-pseudocloso-3,1,2-RuC2B9H9) (1′,8′-Ph2-closo-2′,1′8′-RuC2B9H9)], a trace amount of a triple cluster species [(1,2-Ph2-pseudocloso-3,1,2-RuC2B9H9)(1′,8′-Ph2-closo-2′,1′,8′-RuC2B9H9)(1″,8″-Ph2-closo-2″,1″,8″-RuC2B9H9)], comprising three (Ph2RuC2B9H9) units linked by η6- coordination of Ph rings to the Ru atoms of the adjacent cluster. The structure of the triple cluster was established by X-ray crystallography, and the potential consequences of its formation are discussed.
