In contrast to N–heterocyclic carbenes, the research on the related N–heterocyclic carbene–phosphinidenes (NHCPs) is still in its infancy. Owning to their σ–donor as well as π–acceptor properties and the availability of two free electron lone pairs at the phosphorus atom, NHCPs qualify as ligands to stabilize electron-deficient compounds. Herein we present the synthesis of an NHC-stabilized tetrylene-phosphinidene, as well as the synthesis of a new bisNHCP ligand, and its coordination properties towards Sn(II) and Si(IV) precursors.
