Selenosalicylate; a little-studied heavy-element analogue of the versatile thiosalicylate ligand

Selenosalicylic acid was synthesised by reacting 2-carboxybenzenediazonium chloride with Na 2 Se 2 followed by reduction of the resulting diselenide with zinc and acetic acid. The deprotonated acid reacted with metal precursors to form selenosalicylate complexes.
