A new class of carbene-stabilized diphosphorus molecules, [L:P-P:L] (L:=N-heterocyclic carbenes (NHCs)) was reported. AsCl3 was added to a stirred slurry of the NHC carbene ligand and hexane at ambient temperature. After stirring for a further 21 h, the solvent was removed in vacuo leading to an off white powder. X ray quality colorless crystals of 1 were isolated from a solution in toluene/THF at ambient temperature. THF was added to a flask containing [L1:AsCl3] and KC3. After stirring the mixture vigorously for 15h at ambient temperature, the solvent was removed in vacuo and the residue was extracted with hexane. Concentrating to 4 mL gave X-ray quality single red crystals of 2 overnight at ambient temperature.
