Abstract

The crystal structure of bis(2-pyrimidinyl) disulfide dihydrate, C 8H6N4S2·2H2O, 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. © 2004 International Union of Crystallography Printed in Great Britain - all rights reserved.
