Abstract

In the crystal of the title co-crystalline adduct, C8H16N4·C8H9ClO, (I), prepared by solid-state reaction, the molecules are linked by intermolecular O—H...N hydrogen bonds, forming aDmotif. The azaadamantane structure in (I) is slightly distorted, with N—CH2—CH2—N torsion angles of 10.4 (3) and −9.0 (3)°. These values differ slightly from the corresponding torsion angles in the free aminal cage (0.0°) and in related co-crystalline adducts, which are not far from a planar geometry and consistent with aD2dmolecular symmetry in the tetraazatricyclo structure. The structures also differ in that there is a slight elongation of the N—C bond lengths about the N atom that accepts the hydrogen bond in (I) compared with the other N—C bond lengths. In the crystal, the two molecules are not only linked by a classical O—H...N hydrogen bond but are further connected by weak C—H...π interactions, forming a two-dimensional supramolecular network parallel to thebcplane.
