A tetragonal polymorph of malonamide, C 3 H 6 N 2 O 2 , is reported. The unit‐cell dimensions, crystallographic symmetry and some aspects of the molecular geometry are significantly different from those of the known monoclinic form [Chieh et al. (1970). J. Chem. Soc. A , pp. 179–184]. An R 3 3 (12) hydrogen‐bonding motif links molecules together into a three‐dimensional network.
