Reaction of Os3(CO)12 (or Os3(CO)10(NCPh)2) with C60 in the benzonitrile/o-dichlorobenzene solution at reflux produces Os3(CO)5(μ-NCHPh)­(μ35-NCPhC60C­(C6H4)­N)­(μ,η4-C60) (2) and Os3(CO)4(NCPh)­(μ-NCHPh)­(μ35-NCPhC60C­(C6H4)­N)­(μ,η4-C60) (3), bearing an unprecedented fullerodiketimide ligand from 1,4-addition of two benzonitrile molecules to the C60 cage.
