title: Anticancer and antifertility agents. II. N,N'-hexamethylenebis(3-pyridinecarboxamide).
abstract: The centrosymmetric molecule N,N'-hexamethylenebis-(3-pyridinecarboxamide), C18H22N4O2, contains a crystallographic centre of inversion, with only half of the molecule constituting the asymmetric unit. There are intermolecular N-H...O = C hydrogen bonds [N...O 2.996(2) A] present in the structure.
