Synthesis and investigation of the low-valent derivatives of Group 14 elements (M= Si, Ge, Sn, Pb) represents an actual scientific task. In our works various polydentate ligands (N,N,N-, N,N,O-, O,N,O-types) were used for obtaining the tetrylenes. Furthermore, the tetrylenes obtained were used as ligands in metal (Pd, Mo, W) complexes. Compounds of Group 14 elements (E = Si, Ge, Sn) with element – element bonds due to the presence of σ-conjugation along the chain of E atoms acquire useful properties typical for unsaturated compounds (intense UV absorption, conductivity, electrochemical reaction, luminescence). The establishment of the dependence of these properties on the structure(nature of the E atom, number of the conjugated E atoms, conformation of the molecule, the electronic nature of the substituents) represents an actual scientific challenge.In this report the recent results obtained in our scientific group are present.
