The S atom acts as a bridge to two neighbouring Pb(II) ions, thereby forming a double thiol-ate chain. Moreover, the coordinating carboxyl-ate O atom forms bridges to the Pb(II) ions in the adjacent chain. The overall coordination sphere of the Pb(II) ion can be described as a highly distorted penta-gonal bipyramid with a void in the equatorial plane between the long Pb-S bonds probably occupied by the stereochemically active inert electron pair. The amino H atoms form N-H⋯S and N-H⋯O hydrogen bonds, resulting in a cluster of four complex units, giving rise to an Acta crystallographica.
