Complexes of the heavy pnictogen elements Sb and Bi of monoanionic (C,N-chelated: Sb, Bi) and dianionic (N,C,N-pincer type: Bi) bulky substituted bis(diphenyl(arylimino)phosphorano)methane H2C(Ph2PNR) 2 (R = 2,6-diisopropylphenyl (dipp)) have been prepared via metathetical reactions, and tautomerism within the monoanionic ligand backbone has been observed. The complexes have been characterized by means of X-ray analysis and NMR studies. The dianionic complex was found to feature the rare structural motif of a formal carbon-bismuth(III) double bond. The molecular structure of the solvate-free potassium salt K[HC(Ph2PNdipp) 2] is reported.
