SOLUTION AND SOLID-STATE STUDIES OF SOME NEW SILICON AND GERMANIUM COMPOUNDS STABILIZED BY TRIDENTATE LIGANDS

The preparation and studies of novel heterocyclic compounds, containin g silicon or germanium, is described. All of them incorporate the is(d ialkylaminomethyl)-4-(1,1-dimethylethyl)phenyl tridentate ligand (Stru ctures 1 - 2,Scheme 1) as a main substructure. The report furnishes se ts of experimental data that further clarify the actual solution and s olid state structures of these new molecules with potentially hyperval ent silicon or germanium centers.
