In the crystal structure of the title salt, C(8)H(11)N(4)O(2) (+)·C(6)H(2)N(3)O(7) (-), the pictrate anion participates in extensive hydrogen bonding with the guanidinium ion group of the cation, linking the mol-ecules through N(+)-H⋯O(-) hydrogen bonds and inter-molecular N-H⋯O and C-H⋯O inter-actions. These hydrogen-bonding configurations involve two three-centre/bifurcated bonds [N-H⋯(O,O)] that are observed between two N atoms from the guanidinium ion group of the cation and the o-NO(2) and ...[more]
