Abstract: In the polymeric title compound, [Pb(C₆H₄NO₂)₂C₆H₆N₄S₂)]_n, the Pb^II ion is located on a twofold axis and coordinated by one N,N'-bidentate diaminobithiazole (DABT) ligand and four O-monodentate isonicotinate anions in a very distorted cis-PbN₂O₄ octahedral geometry. The carboxylate group of the isonicotinate anion bridges two Pb^II ions, forming a polymeric chain. The complete DABT molecule is generated by twofold symmetry; its two thiazole rings are twisted with a dihedral angle of 9.5 (2)°. There are no - stacking interactions in the title compound, but N-HO and N-HN hydrogen bonds help to stabilize the structure.
