In the crystal structure of the title compound, C4H13N52+·2NO3−, the main intermolecular interactions are the N—H.O hydrogen bonds between the cationic amino groups and the O atoms of the nitrate ions.All amino H Protection atoms and nitrate O atoms are involved in the three-dimensional hydrogen-bond network.There are two graph-set motifs R22(8), which include the amino groups connected to the N atoms in the biguanide 3-, 4- and 5-positions, and the O atoms of a nitrate ion.They are extended along the a axis.
An O atom of the second nitrate ion is involved in a graph-set motif C(4) that is a part of a helix-like N—H.O.H—N—H.O.chain oriented along the b axis.
There are also two weak C—H.O interactions in Custom Tote Bag the crystal structure.
