Pyrimidine-4-carb­oxy­lic acid

K. Kiegiel, W. Starosta and J. Leciejewicz

Abstract: The crystal structure of the title compound, C5H4N2O2, is built of acid mol­ecules located on a mirror plane. They form sheets stacked along the b-axis direction. The mol­ecules inter­act via O-H...N hydrogen bonds, forming [001] chains, and weak van der Waals inter­actions.
