Abstract
Cp2Cd.TMEDA 1 and Cp2Cd.PMDETA 2 have been synthesized and characterized by spectroscopic studies and by X-ray diffraction studies at low-temperature (153 K). The adducts are present in the crystals as mononuclear complexes. When the denticity of the Lewis base ligands in these adducts is increased (from two in 1 to three in three in 2) the Cd2+ centre requires less electron density from the Cp ligands and the hapticity changes from η2- in 1 to η1- in 2. Complexes 1 and 2 are the first compounds for which π-bonding of Cp ligands to Cd2+ has been observed in the solid state.
