2,2′-o-Phenylenebis(1,3-dimethylguanidine)

The title compound, C16H28N6, was obtained from the reaction of o-phenyl­enediamine with N,N,N′,N′-tetra­methyl­form­amidinium chloride. The two guanidyl groups are almost coplanar with the benzene ring. Both C—N bonds adjacent to the benzene ring were found to be double bonds, while the others were identified as single bonds, based on their bond distances.
