摘要

The crystal structure of hydrate adduct of 6-benzylaminopurine and 5-sulfosalicylic acid [(C~(12)H~(12)N~5) (C ~7H~5O~6S).H~2O] 1 is studied. It crystallizes in monoclinic system space group P21 with a = 6.2128(9) ?, b = 20.762(3) ?, c = 15.675(2) ?, β = 92.040(2), V = 2,020.6(5) ? 3, Z = 4, R_(gt)(F) = 0.0494, wR_(ref)(F ~2) = 0.1112, and T = 173(2) K. Single-crystal X-ray diffraction analysis reveals that the asymmetric unit of 1 contains one 6-benzylaminopurine molecule and one 5-sulfosalicylic acid molecule, as well as one lattice water molecule. In 1, hydrogen bonds link the two monomers into one-dimensional double chain, two-dimensional layer network, and further a 3-D supramolecular network. Short ring-interactions with intra-chain π-π stacking are observed (distances between ring centroids are 3.964, 3.796 and 3.571 ?, and the dihedral angle between planes are 6.97°, 5.55°, and 5.66°, respectively).
