Silicon dioxide as a molecular reagent
Carbon dioxide is a ubiquitous stable gaseous molecule with O=C=O bonding. Yet in one of the quirks of the periodic table, silicon dioxide—the next heaviest group 14 dioxide—is remarkably unstable as a monomeric species. There’s plenty of SiO2 around, but it forms network structures, for example in sand, held together by Si–O single bonds. Chemists have looked for the means to create molecules containing individual O=Si=O units and have come close . . .
