✦ Synopsis

An orthorhombic 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] and of the tetragonal form described in the previous paper [Nichol & Clegg (2005). Acta Cryst. E61, o3424-o3426]. A simple R 4
