title: (1R,2S)-N,N'-(1,2-Dihydroxy-ethyl-ene)diformamide.
abstract: The asymmetric unit of the title compound, C(4)H(8)N(2)O(4), contains one half-mol-ecule which is completed via a crystallographic inversion centre. In the crystal structure, mol-ecules are arranged in undulating layers parallel to (001). Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds consolidate this arrangement.
