A. Koll et P. Wolschann, MANNICH-BASES AS MODEL COMPOUNDS FOR INTRAMOLECULAR HYDROGEN-BONDING .1. SOLID-STATE STRUCTURES AND MOLECULAR CALCULATIONS, Monatshefte fuer Chemie, 127(5), 1996, pp. 475-486
A survey of the structures and the properties of the hydrogen bonds in
ortho-aminomethyl-phenols and -naphthols in the solid state is presen
ted. The results are compared with molecular structure calculations. T
he solid state complexes can exist in the molecular or in zwitterionic
form. In the last case, only intermolecular hydrogen bonds forming cy
clic dimers or linear chains were detected.
