Abstract

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.

Additional information

On the occasion of the 65th anniversary of the foundation of A. N. Nesmeyanov Institute of Organoelement Compounds of the Russian Academy of Sciences.

“Symbiotic” clusters are the clusters in which the substituent (Ph in this case) of one unit is coordinated to the metal center (Ru in this case) of the other unit and vice versa.
