The title compound, [Re(C₃H₆NS₂)(C₂H₃N)(CO)₃], features an octahedrally coordinated Re^I atom within a C3NS2 donor set defined by three carbonyl ligands in a facial arrangement, an acetonitrile N atom and two S atoms derived from a symmetrically coordinating dithiocarbamate ligand. In the crystal, dithiocarbamate-methyl-H⋯O(carbonyl) interactions lead to supramolecular chains along [36-1]; both dithiocarbamate S atoms participate in intramolecular methyl-H⋯S interactions. Further but weaker acetonitrile-C - H⋯O(carbonyl) interactions assemble molecules in the ab plane. The nature of the supramolecular assembly was also probed by a Hirshfeld surface analysis. Despite their weak nature, the C - H⋯O contacts are predominant on the Hirshfeld surface and, indeed, on those of related [Re(CO)₃(C₃H₆NS₂)L] structures.
