Direct detection of intramolecular Sb···N nonbonded interaction by 1H– 13C and 1H– 15N heteronuclear multiple bond correlation spectroscopy

Direct evidence of intramolecular Sb···N nonbonded interaction was obtained by means of 1H– 13C and 1H– 15N heteronuclear multiple bond correlation (HMBC) experiments. The long-range coupling constants between 1H and 13C nuclei through antimony and nitrogen were also determined by the J–HMBC 2D meth...
