The title zinc bis-(thio-semicarbazone) complex, [Zn(C 22 H 17 N 4 O 2 S) 2 ], comprises two N , S -donor anions, leading to a distorted tetra-hedral N 2 S 2 donor set. The resultant five-membered chelate rings are nearly planar and form a dihedral angle of 73.28 (3)°. The configurations about the endocyclic- and exocyclic-imine bonds are Z and E , respectively, and that about the ethyl-ene bond is E . The major differences in the conformations of the ligands are seen in the dihedral angles between the chelate ring and nitro-benzene rings [40.48 (6) cf . 13.18 (4)°] and the N -bound phenyl and nitro-benzene ring [43.23 (8) and 22.64 (4)°]. In the crystal, a linear supra-molecular chain along the b -axis direction features amine-N-H⋯O(nitro) hydrogen bonding. The chains assemble along the 2 1 -screw axis through a combination of phenyl-C-H⋯O(nitro) and π(chelate ring)-π(phen-yl) contacts. The double chains are linked into a three-dimensional architecture through phenyl-C-H⋯O(nitro) and nitro-O⋯π(phen-yl) inter-actions.
