Abstract

The crystal structure and electronic charge distribution of oxamide (oxalic acid diamide, C2N202H4) have been determined at 293 K by X-ray methods. The structural results of Ayerst & Duke [Acta Cryst. (1954), 7, 588-590] have been confirmed. High-order data [up to (sin 0)/2 = 1.15 A -~] were collected. A clear indication of bonding features is obtained. The effect of data cut-off on the difference density map has been investigated.
