The synthesis of organic–inorganic hybrid materials, microporous carbon and fluorine-doped mesoporous silica by the twin polymerization of pentacoordinated fluoridosilicates is reported.

The synthesis and characterization of silicon amidoalkoxides based on 6‐tert‐butyl‐2‐[(2,6‐diisopropylphenyl)aminomethyl]phenol is described. Reaction of its lithium salt with HSiCl3 and SiCl4 gave HSiCl[OC6H3(CH2NDipp)‐2‐tBu‐6] (2) and Cl2Si[OC6H3(CH2NDipp)‐2‐tBu‐6] (5) (Dipp = 2,6‐diisopropylphenyl), respectively. The silicon amidoalkoxide 2 reacts with tBuLi and LiN(SiMe3)2 to give the chiral silanes HSi(tBu)[OC6H3(CH2NDipp)‐2‐tBu‐6] (3) and HSi[N(SiMe3)2][OC6H3(CH2NDipp)‐2‐tBu‐6] (4). The amidoalkoxide based hydridosilicate [HSi{OC6H3(CH2NDipp)‐2‐tBu‐6}2]K (6) was isolated upon reaction of compound 5 with potassium. The molecular structure of compounds 4 and 6 was determined by single‐crystal X‐ray diffraction studies. Notably, compound 6 is the first silicate of the type [HSiN2O2]–.

We report on the synthesis of a new bismuth aryloxide molecule Bi[OC6H4(CH2C6H5)-2]3 (1), which was characterized by NMR and IR spectroscopy as well as single-crystal X-ray diffraction analysis. A characteristic structural feature is the dimeric unit with a central Bi2O2 core resulting from μ-binding phenolates. In addition, both bismuth atoms show a Bi⋅⋅⋅π arene interaction with a quite short Bi⋅⋅⋅πcentroid distance of 3.11 Å in the solid state.
