Abstract
The title complex, [Pb(C(8)H(5)N(2)O(2)S)(2)](n), consists of one Pb(II) ion located on a crystallographic twofold axis and two symmetry-related 2-amino-1,3-benzothia-zole-6-carboxyl-ate (ABTC) ligands. The central Pb(II) ion has a (4 + 2) coordination by four O atoms of the two ABTC ligands and two weaker Pb-S bonding inter-actions (Pb-S secondary bonds) from S atoms of other two neighbouring ABTC ligands. These bonds link the metal ions into zigzag chains along the c axis, which, in turn, aggregate through π-π inter-actions [centroid-centroid distance = 3.7436 Å] between ABTC rings and N-H⋯O and N-H⋯N hydrogen bonds.
