title: Bis{3-[2-(methyl-sulfon-yl)pyrimidin-4-yl]pyridinium} tetra-chloridocadmium.
abstract: In the title compound, (C(10)H(10)N(3)O(2)S)(2)[CdCl(4)], the Cd(II) ion lies on a twofold axis and is coordinated by four chloride anions, with bond distances of 2.4787 (10) and 2.4410 (10) Å. A chain along the c axis is formed by C-H⋯N hydrogen-bonding inter-actions and a weak π-π inter-action is observed between the pyrimidine rings of two adjacent parallel chains [centroid-centroid distance = 3.722 (2) Å]. N-H⋯Cl, CN-H⋯Cl and N-H⋯O interactions also occur.
