The title complex, Pb(C(8)H(5)N(2)O(2)S)(2), 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.
标题配合物[Pb(C₈H₅N₂O₂S)₂]ₙ由位于晶体学二重轴上的一个Pb(II)离子和两个对称相关的2-氨基-1,3-苯并噻唑-6-羧酸酯（ABTC）配体组成。中心Pb(II)离子通过两个ABTC配体的四个O原子形成(4 + 2)配位，以及来自其他两个相邻ABTC配体的S原子的两个较弱的Pb-S键相互作用（Pb-S二级键）。这些键沿着c轴将金属离子连接成锯齿链，这些链又通过ABTC环之间的π-π相互作用[质心-质心距离 = 3.7436 Å]以及N-H⋯O和N-H⋯N氢键聚集。
