Crystal structure of bis{2-[amino(iminiumyl)methyl]-1,1-dimethylguanidine} carbonate methanol disolvate

Abstract

In the title solvated molecular salt, 2C4H12N5+·CO32−·2CH3OH, the complete carbonate ion is generated by crystallographic twofold symmetry, with the C atom and one O atom lying on the rotation axis. The cation is twisted about the central C—N bond [C—N—C—N = −137.7 (6)°]. In the crystal, the components are linked by N—H...O, N—H...N and O—H...O hydrogen bonds, generating a three-dimensional supramolecular network.
