Triorganosilicon (IV) compounds: synthesis, structural study, and biological activity.
A few coordination compounds of silicon (IV) have been synthesized by the interaction of trimethyl- and triphenyl-chlorosilane with nitrogen-sulphur donor ligands. These compounds are monomeric, as indicated by molecular weight determination, and they behave as nonelectrolytes in dry DMF. From the electronic, infrared, 1H, and 13C NMR spectral results, it has been concluded that in these compounds, silicon is penta-coordinated in a trigonal bipyramidal environment. An assessment of biological activity of these compounds has shown that some of them are very active against P. mirabilis and others against S. viridans bacteria, while all of them show good fungicidal action against F. oxysporum, A. alternata, and A. niger.
