Stable up to 100° , the yellow crystals of the title compound 1 can be obtained in good yields from PbCl 2 and the appropriate lithiated pyrrole. Compound 1 shows the bent structure characteristic for metallocenes of elements of Group 14 (the side view is reproduced without t Bu substituents) and unlike plumbocene is monomeric in the solid state.
