In the title compound, 2C13H14N3+·C 2O2-4, the anion is at an inversion centre. The cation has approximate C2 symmetry, with the two phenyl rings oriented anti with respect to the unsubstituted N atom. Bond lengths and angles within the guanidinium moiety are close to those expected for a central Csp2 atom with a small charge delocalization between the three C-N bonds. The anions and cations are interconnected by a two-dimensional hydrogen-bonding network extended in the (100) plane.
