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.
