meso-3,6-Dioxopiperazine-2,5-diacet­amide

The title compound, C(8)H(12)N(4)O(4), was obtained by cyclization of the two l-asparagine mol­ecules and reveals a crystallographic inversion symmetry, and accordingly the two stereogenic centres are of opposite chirality. Thus, an asymmetric unit comprises a half of a mol­ecule. The mol­ecules are...

description The title compound, C(8)H(12)N(4)O(4), was obtained by cyclization of the two l-asparagine mol­ecules and reveals a crystallographic inversion symmetry, and accordingly the two stereogenic centres are of opposite chirality. Thus, an asymmetric unit comprises a half of a mol­ecule. The mol­ecules are assembled into a three-dimensional hydrogen-bonding network by N—H⋯O hydrogen bonds.
