Crystal and molecular structure of 5-carboxy-2-thiouracil monohydrate

The structure determination of 5-carboxy-2-thiouracil shows it to exist in the lactam-thione form. Extensive hydrogen bonding involving all possible donors and acceptors leads to the formation of interconnected 8- (x2), 10-, 16- and 20-membered rings and a two-dimensional layer structure; no evidence for base stacking was found.
