N,N'-Bis(dipiperidin-1-ylmethylene)propane-1,3-diamine and N,N'-bis(1,3-dimethylperhydropyrimidin-2-ylidene)propane-1,3-diamine.
The molecular structures of the title compounds, C(25)H(46)N(6) and C(15)H(30)N(6), respectively, show the two guanidyl moieties each connected by propyl bridges. The different substitution pattern of the guanidyl groups has no influence on the distinct localization of their C=N double bonds. Both compounds exhibit approximate twofold symmetry and the crystal packing shows no prominent hydrogen-bonding interactions.
