摘要：

The title compound (systematic name: 2,4-dihydroxy-5-iodo-pyrimidine), C4H3IN2O2, which was first reported by Sternglanz, Freeman & Bugg [ Acta Cryst. (1975), B31, 1393-1395], has been redetermined, providing a significant increase in the precision of the derived geometric parameters. The asymmetric unit comprises a non-planar molecule in a slightly distorted B-25 boat conformation. The molecules are associated in the crystal structure to form ribbons stabilized by N-H center dot center dot center dot O hydrogen bonds which involve NH groups and two carbonyl O atoms.
