Monoanion BH4(-) can stabilize zwitterionic glycine with dihydrogen bonds.
Unusual strength: In the complex glycine-BH(4)(-), unconventional dihydrogen bonds are predicted. An ultrashort dihydrogen bond B-H...H-N 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.
