摘要：

The title compound, C4H8N6O2, represents a virtually unknown vicinal orthoamide array, formally derivable from oxalic acid. The cis-fused imidazolidinone rings adopt a flattened envelope conformation. H atoms of the nearly eclipsed vicinal diamine groups [N1-C1-C5-N5 -9.5(3)degrees] are oriented inwards [H1a ... H5a = 2.44(4) and H1b ... H5b = 2.49 (4) Angstrom].
