Dramatic deviations from ideal tetrahedral geometry and destabilization despite contracted bond lengths —these features of the series of fluoro(methyl)plumbanes are revealed by ab initio pseudopotential calculations. In Me 2 PbF 2 ( 1 ) (calculated structure depicted), the C‐Pb‐C angle is almost 135°! The introduction of fluorine substituents thus has markedly different effects on plumbanes than on alkanes and silanes.
