Abstract: All six Ag^I atoms of the title compound, [Ag₆(₃-C₅H₄NS)₆], are bridged through the six S atoms of the six pyridine-2-thiolate ligands to form an Ag₆ cluster. Each of the six Ag^I atoms exhibits a distorted trigonal coordination geometry, with two thiolate S atoms and an N atom from three pyridine-2-thiolate ligands. The Ag-S distances are in the range 2.459 (3)-2.488 (3) Å and the Ag-N bond distances range from 2.307 (8) to 2.320 (8) Å. Each thiolate S atom bridges two Ag^I atoms. In the hexamer, the six Ag^I atoms are in a nearly perfect octahedral configuration and this hints at a weak Ag^IAg^I interaction. The molecule is located on a centre of inversion, with only one half constituting the asymmetric unit.
