Coupling reaction of alkyl cyanide (RCN, R = Me or Et) with 7-azaindole on a hexaosmium carbonyl cluster core; molecular structure of [Os6(CO)14(µ-CO)(µ-H)(µ-η1:η2-C9H8N3)]

Treatment of [Os6(CO)16(NCR)2] (R = Me or Et) with 7-azaindole resulted in the formation of [Os6(CO)14(µ-CO)(µ-H)(µ-η1∶η2-C8H5N3)(R)] involving coupling of the alkyl cyanide and 7-azaindole
