A. Tanatani et al., (CIS)-PREFERENCE OF N,N'-DIMETHYL-N,N'-DIPHENYLGUANIDINE AND THE GUANIDINIUM SALT - CONSTRUCTION OF WATER-SOLUBLE AROMATIC LAYERED STRUCTURE, Chemical and Pharmaceutical Bulletin, 44(5), 1996, pp. 1135-1137
N,N'-Dimethyl-N,N'-diphenylguanidine (2a) and the corresponding guanid
inium salt (2b) have crystal structures in which two phenyl groups are
located face-to-face. Similar (cis, cis) conformations were also obse
rved in various solvents. These structures may be useful as key buildi
ng blocks to construct water-soluble aromatic layered molecules.
