A zwitterionic carbene–plumbylene adduct

Abstract

4,5-Dimethyl-1,3-diisopropylimidazol-2-ylidene reacts with bis(2,4,6-triisopropylphenyl)plumbylene to furnish the adduct 4 as yellow crystals; an X-ray structure analysis of 4 revealed a very long lead–carbon bond of 254.0(5) pm and a pyramidal lead centre with a bending angle of 70.5°.
