Reported the crystal structure of 1,2-diethoxy carbonyl hydrazine. The title compound （C6H12N2O4） is characterized by X ray single-crystal diffraction. The crystal belongs to Monoclinic system, C2/c space group with α=13. 283 0 （18）A^°,b=8. 738 3 （12）A^°,c=7. 672 9 （10）A^°,β-97. 390 （2）A^°,V=883.2 （2）A^°3 ,Mr=176.18,Z=4. The two groups are almost parallel to each other and point to the same direction. Two molecules in the unit cell are linked by a pair of N-H…O hydrogen bonds between the amino H atom and the carbonyl oxygen atom to form a centrosymmetric dimer. The crystal structure is built up from a stacking of these dimers such that the inter-dimer interactions are mainly of van der Waals type.
