Abstract The title compound was synthesized and its crystal structure determined by single crystal X-ray diffraction techniques. It crystallizes in the monoclinic system witha=9.390(1),b=9.688(2),c=13.828(3)Å,β=110.16(2)°, space groupP21/c,Z=4. The structure was solved by direct methods and refined by full-matrix least-squares calculations toR=0.032 for 1968 reflections withI〉3σ(I) [MoKα radiation]. The six-membered ring of the 5,6-dihydrouracil-6,6-disulfonate dianion displays an approximate skew-boat conformation, but the ring puckering differs from that commonly observed in 5,6-dihydrouracil derivatives. The coordination to two crystallographically independent K+ ions which exhibit different coordination geometries links anions, cations and water molecules in an infinite three-dimensional network.
