Abstract
The chiral thallium amidinium cyclopentadiene-N-ylide complexes [C-5(CO2Me) (4){ArNC(Ar ' )NAr}]Tl were synthesized and structurally characterized by X -ray diffraction analysis and NMR spectroscopy. In these complexes, an unus ual mode of coordination of the thallium atom was found, viz., the thallium atom is coordinated by both the side-chain nitrogen atom (N-Tl, 2.833(6) A ngstrom) and the pi system of the cyclopentadienyl ring (Tl-Cp, 2.887(4) An gstrom; eta (5)-bonding).
