Guanidinium phenylarsonate–guanidine–water (1/1/2)

Abstract

In the structure of the title compound, CH6N3+·C6H6AsO3−·CH5N3·2H2O, the phenylarsonate anion participates in two R22(8) cyclic hydrogen-bonding interactions, one with a guanidinium cation, the other with a guanidine molecule. The anions are also bridged by the water molecules, one of which completes a cyclic R53(9) hydrogen-bonding association with the guanidinum cation, conjoint with one of the three R22(8) associations about that ion, as well as forming an R21(6) cyclic association with the guanidine molecule. The result is a three-dimensional framework structure.
