| Abstract: | Abstract The crystal structure of nonane-1,9-diaminium chloride chloroacetate–hydroxyacetic acid (1:1) was determined by X-ray diffraction at 100(1)K. The asymmetric unit is composed of diaminium dication, chloroacetate and chloride anions, and neutral hydroxyacetic acid molecule. The aliphatic chain of 1,9-diamine is fully extended and it deviates only slightly from the perfect all-trans conformation. The two acidic residues are also nearly planar. The layer structure is obtained as a consequence of hydrogen bond interactions of a different lengths, with N–H and O–H groups playing the role of donors and oxygen atoms and chloride cations as acceptors. The pattern of H bonding is investigated by graph-set analysis. Crystal data: crystal system: monoclinic, a = 4.6418 (2) ?, b = 25.5128 (11) ?, c = 15.9943 (9) ?, β = 99.784 (5)°, Z = 4, space group: P21/c, V = 1866.6(1) ?3. |
