In 2,2,2-trichloro-N,N'-bis(4-methoxyphenyl) ethane-1,1-diamine, C16H17Cl3N2O2, molecules are linked into helical chains by N - H center dot center dot center dot O hydrogen bonds. Molecules of 2,2,2-trichloro-N, N'-bis(4-chlorophenyl) ethane-1,1-diamine, C14H11Cl5N2, are connected into a three-dimensional framework by two independent Cl center dot center dot center dot Cl interactions and one C - H center dot center dot center dot Cl hydrogen bond.
