The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

The title compound [systematic name: ammonium pyrimidine-2,4-5,6(1H,3H)- tetrone 5-oximate], NH4 +·C4H2N3O4 -, crystallizes from water in the triclinic space group P and is isomorphous with a known rubidium complex [Gillier (1965). Bull. Soc. Chim. Fr. pp. 2373-2384]. The principal feature of the structure is hydrogen bonding; each ammonium H atom acts as a bifurcated donor and three of the four violurate O atoms are bifurcated acceptors, with the fourth acting as a trifurcated acceptor. The pattern of hydrogen bonding around the cation is very similar to the rubidium coordination environment in the related structure. The violurate anions pack as hydrogen-bonded crinkled tapes, which are linked and separated by the ammonium cations to give a compact three-dimensional structure. © International Union of Crystallography 2007.
