The title CuII complex, [Cu(C13H11N2OS2)2], features a trans-N2S2 donor set as a result of the CuII atom being located on a crystallographic centre of inversion and being coordinated by thiolate-S and imine-N atoms derived from two dithiocarbazate anions. The resulting geometry is distorted square-planar. In the crystal, π(chelate ring)–π(furyl) [inter-centroid separation = 3.6950 (14) Å and angle of inclination = 5.33 (13)°] and phenyl-C—H...π(phenyl) interactions sustain supramolecular layers lying parallel to (\overline{1}02). The most prominent interactions between layers, as confirmed by an analysis of the calculated Hirshfeld surface, are phenyl-H...H(phenyl) contacts. Indications for Cu...Cg(furyl) contacts (Cu...Cg = 3.74 Å) were also found. Interaction energy calculations suggest the contacts between molecules are largely dispersive in nature.

The crystal structures of the disordered hemi-DMSO solvate of (E)-2-oxo-N′-(3,4,5-trimethoxybenzylidene)-2H-chromene-3-carbohydrazide, C20H18N2O6·0.5C2H6OS, and (E)-N′-benzylidene-2-oxo-2H-chromene-3-carbohydrazide, C17H12N2O3 (4: R = C6H5), are discussed. The non-hydrogen atoms in compound [4: R = (3,4,5-MeO)3C6H2)] exhibit a distinct curvature, while those in compound, (4: R = C6H5), are essential coplanar. In (4: R = C6H5), C—H...O and π–π intramolecular interactions combine to form a three-dimensional array. A three-dimensional array is also found for the hemi-DMSO solvate of [4: R = (3,4,5-MeO)3C6H2], in which the molecules of coumarin are linked by C—H...O and C—H...π interactions, and form tubes into which the DMSO molecules are cocooned. Hirshfeld surface analyses of both compounds are reported, as are the lattice energy and intermolecular interaction energy calculations of compound (4: R = C6H5).
