The crystal structure of the title compound, [Zn(C5H5NS)4](NO3)2, consists of a [Zn(C5H5NS)4]2+ (C5H5NS is pyridinium-2-thiolate) cation and two nitrate anions. The central ZnII atom lies at a site with imposed symmetry and is surrounded by four S atoms [Zn—S = 2.3371 (5) Å] from four symmetrical pyridinium-2-thiolate ligands in a distorted tetrahedral geometry. There are N—H…O hydrogen-bonding interactions between the pyridinium-2-thiolate ligands and nitrate O atoms. In addition, – interactions via aromatic N-containing ligands are discussed.
