1,3-Diphenylguanidinium Trifluoroacetate

The two phenyl rings of the title compound, C₁₃H₁₄N₃⁺.CF₃CO₂^-, assume a syn conformation with respect to the unsubstituted N atom of the cation. Bond lengths and angles within the guanidinium moiety are close to those expected for a central C_sp² atom, accounting for some charge delocalization between the three C-N bonds. The structure is stabilized by a two-dimensional network of intermolecular hydrogen bonds, where the carboxylate O atoms of the anions are acceptors from the N-H groups of the diphenylguanidinium cations.
