The synthesis of two new dithiols, 1,8‐dimercapto‐2,7‐di( tert ‐butyl)naphthalene (H 2 L 1 ) and 1,8‐dimercaptonaphthoic anhydride (H 2 L 2 ), is described. They react with diethylzinc to yield the polymeric complexes L 1 Zn and L 2 Zn. L 1 Zn dissolves in the presence of pyridine to form [L 1 Zn·py] x , which is presumed to be dimeric. Both L 1 Zn and L 2 Zn react with neocuproin. Structure determinations have confirmed the tetrahedral ZnN 2 S 2 coordination in the resulting LZn·neo complexes.
