The first thorium poly-carbene complexes [(Ph2PS)2C]2Th(DME) (2) and [{[(Ph2PS)2C]3Th}Li2(DME)]n (3) have been prepared and structurally characterized. DFT calculations reveal that the ThC bond is polarized toward the nucleophilic carbene carbon atom, which is further verified by the experimental observation that the ThC bond shows a nucleophilic behavior with Ph2CO.
