Özet

In the asymmetric unit of the title compound, C10H15N4O2+center dot H2PO4-, there are two protonated aminoguanidinium cations and two dihydrogenphosphate anions. The positive charge on the protonated amidine group is delocalized over the three C - N bonds in a manner similar to that found in guanidinium salts. The aminoguanidinium cations are found to be the E-isomer structures. Intramolecular interactions of the N - H center dot center dot center dot N type are observed, leading to the formation of five-membered rings. Extensive networks of O - H center dot center dot center dot O, N-H center dot center dot center dot O and C - H center dot center dot center dot O hydrogen bonds stabilize the three-dimensional network. In the crystal structure, pi-pi interactions between the benzene rings, with a distance of 3.778 (2) angstrom between the ring centroids, also affect the packing of the molecules.
