The hitherto unknown compounds 2‐(2′‐thieny1)‐pyridine and methyl α‐picolyl sulphide have been synthesized. The stability constants of Ni 2+ , Cu 2+ and Zn 2+ complexes with these two substances and with pyridine, α‐picoline, β‐picoline, γ‐picoline, and 2‐phenylpyridine have been measured and are discussed. Evidence for the coordination of the sulphur atom in methyl α‐picolyl sulphide as well as in the aromatic 2‐(2′‐thieny1)‐pyridine is given. It is also shown that thiophene is able to coordinate to Cu 2+ .
