2,2′:6′,2″-Terpyridine-4′(1′H)-thione: a missing link in metallosupramolecular chemistry†
Abstract
The compound 2,2′:6′,2″-terpyridine-4′(1′H)-thione 1 has been prepared and structurally characterised; in both the solid state and in solution, the thione tautomer is dominant. Compound 1 is a key entry into 4′-sulfur-functionalised tpy
