A low-temperature redetermination of the title compound, C 12H16N2O3, more commonly known as hexobarbitone, is reported, with significantly improved precision. The crystal packing reveals an infinite hydrogen-bonded hexobarbitone chain linked by a single N-H⋯O interaction, an extremely rare motif in barbiturate crystal packing. Unlike some other barbiturate crystal structures, there is no phase transition on cooling to 150 K. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
