The title compound, [Pb(C 4 H 3 N 2 S) 2 ] n , was prepared by the reaction of [Pb(OAc) 2 ]·3H 2 O (OAc is acetate) with pyrimidine‐2‐thione in the presence of triethylamine in methanol. In the crystal structure, the Pb II atom has an N 4 S 4 coordination environment with four ligands coordinated by N‐ and S‐donor atoms. This compound shows that the pyrimidine‐2‐thiolate anion can lead to a three‐dimensional network when the coordination number of the metal ion can be higher than 6, as is the case with the Pb II ion. This compound presents only covalent bonds, showing that despite the possibility of the hemidirected geometries of Pb II , the eight‐coordinated ion does not allow the formation of an isolated molecular structure with pyrimidine‐2‐thiolate as the ligand.
