Two nutrients in one molecule:
A zwitterionic λ5Si,λ5Si′-disilicate (1) was synthesized and characterized. It contains ligands that exclusively derive from natural products ((R,R)-tartaric acid, choline). Hydrolysis of 1 yields 2, which shows a remarkable kinetic stability in water. Upon dissolution of 1 and 2 in water, the nutrients choline and orthosilicic acid are formed by hydrolysis

A series of novel neutral pentacoordinate silicon(IV) complexes with SiClSN2C, SiBrSN2C, SiSN3C, SiSON2C, SiS2N2C, SiSeSN2C and SiTeSN2C skeletons (compounds 1–12) was synthesised, starting from PhSiCl3, PhSiBr3, PhSi(NCO)3, MeSiCl3 or C6F5SiCl3. Compounds 1–12 contain (i) a tridentate dianionic N,N,S chelate ligand (derived from 2-{[(pyridin-2-yl)methyl]amino}benzenethiol), (ii) a phenyl, methyl or pentafluorophenyl group and (iii) a monodentate monoanionic ligand (Cl, Br, NCO, NCS, N3, OS(O)2CF3, OPh, SPh, SePh, TePh). The pentacoordinate silicon(IV) complexes 1–12 were characterised by elemental analyses, NMR spectroscopic studies in the solid state and in solution and crystal structure analyses. These experimental investigations were complemented by computational studies.
