Hexa-kis-(?3-2-hy-droxy-naphthalene-1-carboxaldehyde thio-semicarbazonato-?(3) N (2):S:S)hexa-silver(I) N,N-dimethyl-formamide tetra-solvate.

ABSTRACT: In the title compound, [Ag6(C12H10N3OS)6]·4C3H7NO, the hexa-nuclear complex mol-ecule lies about an inversion center. The six Ag atoms form a distorted octa-hedron, with Ag?Ag distances in the range 2.933?(1)-3.401?(1)?Å. Each Ag atom is surrounded by one N atom and two thiol-ate S atoms from two deprotonated 2-hy-droxy-1-naphthaldehyde thio-semi-carb-a-zone ligands. Each ligand coordinates three Ag atoms via a bridging thiol-ate S atom and a monodentate N atom, thus two Ag3S3 hexa-gonal rings are linked together. Two dimethyl-formamide solvent mol-ecules are located in four sets of sites with half-occupancy and form O?H-N hydrogen bonds to the complex mol-ecule. Intra-molecular O-H?N hydrogen bonds are also present. The discrete hexa-nuclear clusters are further linked through ?-? inter-actions into layers parallel to (001), the shortest distance between the centroids of aromatic rings being 3.698?(2)?Å.
