Struktur eines Blei(II)‐Komplexes mit verknüpften Monothioquadratationen als Liganden

A Lead(II) Complex with Linked Monothiosquarate Ions as Ligands The thiosquarate ligand bis‐1,2‐(2‐hydroxy‐3,4dione‐cyclobut‐1‐enylsulfanyl)‐ethane and its lead(II) complex have been prepared. According to the crystal structure analysis the complex has a unique layer structure in the solid state. The layers consist of a superposition of cyclic dimeric complexes and of chain like polymeric complexes. The shortest nonbonding Pb…Pb distances are 4.0 Å.
