Two-Dimensional Condensation of Guanidinium Nitrate at the Mercury-Water Interface

Article abstract of DOI:10.1021/j100141a037

Guanidinium cations can form a condensed interfacial monolayer with nitrate anions, in which the two ions participate in a one-to-one ratio.The earlier results of Dyatkina et al. (Elektrokhimiya 1980, 16, 996) have been confirmed and extended.The formation of the monolayer film is controlled by the kinetics of nucleation and two-dimensional growth.Most likely, the film is held together by multiple hydrogen bonds between the nitrate oxygens and the amine hydrogens of the guanidinium ions, in an interfacial organization similar to that in the layered crystal structure reported here.
