Unusual strength: In the complex glycine–BH 4 − , unconventional dihydrogen bonds are predicted. An ultrashort dihydrogen bond BH⋅⋅⋅HN and a very strong interaction of about −41 kcal mol −1 ) are found in complex 3 (see structures), in which the zwitterionic glycine is stabilized with a big margin.
