title: Tetrakis(pyridinium-2-thiolato)zinc(II) dinitrate.
abstract: The crystal structure of the title compound, [Zn(C(5)H(5)NS)(4)](NO(3))(2), consists of a [Zn(C(5)H(5)NS)(4)](2+) (C(5)H(5)NS is pyridinium-2-thiolate) cation and two nitrate anions. The central Zn(II) atom lies at a site with imposed -4 symmetry and is surrounded by four S atoms [Zn-S = 2.3371 (5) A] 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, pi-pi interactions via aromatic N-containing ligands are discussed.
