Abstract
In 2,2,2-trichloro-N,N'-bis(4-methoxyphenyl)ethane-1,1-diamine, C(16)H(17)Cl(3)N(2)O(2), molecules are linked into helical chains by N-H...O hydrogen bonds. Molecules of 2,2,2-trichloro-N,N'-bis(4-chlorophenyl)ethane-1,1-diamine, C(14)H(11)Cl(5)N(2), are connected into a three-dimensional framework by two independent Cl...Cl interactions and one C-H...Cl hydrogen bond.
