Аннотация:Organic polydentate ligands are widely used in the chemistry of Group 14 elements (E = Si, Ge, Sn, Pb), modifying the stability, structure and properties of the ring systems obtained. In the structure of these ligands it is possible to change the type of donor atoms (O, N, S), denticity, the length of the chelate arms.
The present report includes our recent results on E(IV) and E(II) derivatives, based on different O-, N-, S-polydentate ligands.
