N2 - The crystal structure of diethyl piperazzine-1,4-diyldioxalate, was analyzed. It was observed that the molecule was located on an inversion center. The one half of molecule was found in asymmetric unit and other half was generated by symmetry. The piperazine ring exhibited a chair conformation, with bond lengths and angles in standard ranges and a mean N-C bond length of 1.48 Å. The results show that four C atoms of piperazine ring were observed as four different signals at 45.5, 44.7, 40.7 and 40.0 p.p.m., in the 13C NMR spectrum.
