title: 2-(2,3-Dioxoindolin-1-yl)ethyl 4-(4-nitro-phen-yl)piperazine-1-carbodithio-ate.
abstract: In the title compound, C(21)H(20)N(4)O(4)S(2, )the piperazine ring adopts a chair conformation. The 1-ethyl-indoline-2,3-dione system links to one N atom of the piperazine ring via a carbodithio-ate group. The indoline-2,3-dione ring and the nitro-benzene ring subtend adihedral angle of 37.27 (7)°. In the crystal structure, weak C-H⋯O and π-π stacking inter-actions [centroid-centroid distances = 3.534 (5) and 3.797 (5) Å] may help to establish the packing.
