C–O bond stretched to record length | Chemistry World - Chemists in the US have stretched the C–O bond to a record length, an ‘extraordinary’ 1.622Å, compared with a typical length of around 1.43Å in ethers. The work not only presents a chemical curiosity, but helps to confirm and contribute to the theoretical understanding of the limits of covalent bonding and the consequences of introducing extreme strain in molecular structures.(10.1038/nchem.1502)
