()-{[(Butyl-sulfan-yl)methane-thio-yl]amino}(4-meth-oxy-benzyl-idene)amine: crystal structure and Hirshfeld surface analysis.

The title hydrazine carbodi-thio-ate, CHNOS, is constructed about a central and almost planar CNS chromophore (r.m.s. deviation = 0.0263 Å); the terminal meth-oxy-benzene group is close to coplanar with this plane [dihedral angle = 3.92 (11)°]. The -butyl group has an extended all- conformation [torsion angles S-C-C-C = -173.2 (3)° and C-C-C-C = 180.0 (4)°; m = methyl-ene and me = meth-yl]. The most prominent feature of the mol-ecular packing is the formation of centrosymmetric eight-membered {⋯HNCS} synthons, as a result of thio-amide-N-H⋯S(thio-amide) hydrogen bonds; these are linked meth-oxy-C-H⋯π(meth-oxy-benzene) inter-actions to form a linear supra-molecular chain propagating along the -axis direction. An analysis of the calculated Hirshfeld surfaces and two-dimensional fingerprint plots point to the significance of H⋯H (58.4%), S⋯H/H⋯S (17.1%), C⋯H/H⋯C (8.2%) and O⋯H/H⋯O (4.9%) contacts in the packing. The energies of the most significant inter-actions, . the N-H⋯S and C-H⋯π inter-actions have their most significant contributions from electrostatic and dispersive components, respectively. The energies of two other identified close contacts at close to van der Waals distances, . a thione-sulfur and meth-oxy-benzene-hydrogen contact (occurring within the chains along the axis) and between methyl-ene-H atoms (occurring between chains to consolidate the three-dimensional architecture), are largely dispersive in nature.
