The molecules of 2,2,2-trichloro-N,N'-diphenylethane-1,1-diamine, C14H13Cl3N2, are linked into ( 040) sheets by a combination of C-H center dot center dot center dot Cl and C-H center dot center dot center dot pi( arene) hydrogen bonds. In 2,2,2-trichloro- N,N'-bis(4-methylphenyl)ethane-1,1-diamine, C16H17Cl3N2, the molecules are linked into C(7) chains by two independent C-H center dot center dot center dot Cl hydrogen bonds and one Cl center dot center dot center dot Cl contact.
