- Аннотация: The synthesis of low-valent derivatives of the Group 14 elements (M = Ge, Sn, Pb) is one of the most important goals in the modern organometallic chemistry. It is well known that the stabilization of such low-valent derivatives is achieved by introduction of the bulky substituents (kinetic stabilization) or by interaction of the vacant orbital of the atom M with electron density from ligand (thermodynamic stabilization). These "heavy carbenes" may be the suitable starting materials for the synthesis of a variety of organometallic compounds and intermediates, for example, transition metal complexes and clusters with group 14 element derivatives as ligands, compounds with multiple bonds of M‑C and M‑heteroatom, small metallacycles, radicals and ions. The aim of this work is the synthesis of new germylenes, stannylenes, plumbylenes based on novel O,N,O- and N,N,O‑type ligands with sterically voluminous substituents. The structure of target compounds was investigated in solution by NMR spectroscopy and in solid state by X-ray analysis. Complexes 6, 9, 13, 17, 18 were investigated by X-ray analysis. In case of the complexes 17 and 18, we can see the influence of ligands on these complexes. If the ligand is more voluminous, we obtain the monoligand complex 17.
