Abstract: In the title compound, [Ag6(C12H10N3OS)6]·4C3H7NO, the hexanuclear complex molecule lies about an inversion center. The six Ag atoms form a distorted octahedron, with AgAg distances in the range 2.933 (1)-3.401 (1) Å. Each Ag atom is surrounded by one N atom and two thiolate S atoms from two deprotonated 2-hydroxy-1-naphthaldehyde thiosemicarbazone ligands. Each ligand coordinates three Ag atoms via a bridging thiolate S atom and a monodentate N atom, thus two Ag3S3 hexagonal rings are linked together. Two dimethylformamide solvent molecules are located in four sets of sites with half-occupancy and form OH-N hydrogen bonds to the complex molecule. Intramolecular O-HN hydrogen bonds are also present. The discrete hexanuclear clusters are further linked through - interactions into layers parallel to (001), the shortest distance between the centroids of aromatic rings being 3.698 (2) Å.
