Bis(2-pyrimidinyl) disulfide dihydrate: a redetermination

G. B. Jensen, G. Smith, D. S. Sagatys, P. C. Healy and J. M. White

Abstract: The crystal structure of bis(2-pyrimidinyl) disulfide dihydrate, C₈H₆N₄S₂·2H₂O, has been redetermined using CCD diffractometer data. This has allowed for a more precise location of the water H atoms and shows the water molecules forming unusual spiral hydrogen-bonded aqua columns, as well as giving inter-column crosslinks through the pyrimidine N-atom acceptors of the disulfide molecules. The structural chemistry of aromatic disulfides has also been reviewed.
