    • Crystallizations were performed in 0.22 mM EtOH in a glass test tube initially sealed with 'parafilm'. This was punctured with a small hole to permit slow evaporation over several days at 27 °C. Colorless crystals were thus obtained, which were collected, dried and used directly for the diffraction study.

    • 3) interactions with the adenine and thymine moieties (Tables 2 and 3 ). These weaken with increase of temperature. On further heating the structure collapses irreversibly. It must be pointed out that the role of water molecules with respect to their hydrogen bonding potentials would be understood more clearly when better quality crystals are obtained. However, sustained effects to get these crystals so far have failed.
