Redetermination of 5-iodouracil

Redetermination of 5-iodouracil

The title compound (systematic name: 2,4-dihydroxy-5-iodopyrimidine), 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. Th...
