Abstract A 1∶1 crystalline adduct of hexamethylenetetramine with phenylacetic acid, (CH2)6N4·C6H5CH2COOH, has been isolated and characterized by X-ray analysis. The compound crystallizes in space groupI¯4 (No. 82), witha=20.576(3),c=6.907(1) Å, andZ=8. The crystal structure is composed of a packing of discrete molecular aggregates corresponding to the stoichiometric formula, each being consolidated by a N⋯H-O hydrogen bond of length 2.643(8) Å, which has no significant effect on the regular geometry of the (CH2)6N4 cage system. The C-CO2 and phenyl groups in the C6H5CH2COOH moiety make a dihedral angle of 74(1)°. The structure has been refined toR=0.071 for 1350 observed (∥F o ∥〉2σ∥F o ∥) MoKα data.
