The adducts of a series of compounds with urea (ur) have been prepared and their crystal structures determined by X-ray crystallography. These are the adducts with the unsaturated aliphatic acids fumaric acid [(fumaric acid)(ur)2] (1) and itaconic acid [(itaconic acid)(ur)] (2), and with cyanuric acid [(cyanuric acid)(ur)] (3). All structures have extensive hydrogen-bonding systems in which most of the urea donor and acceptor sites are involved.
