Abstract
Complexes of 2-(1,2,3-thiadiazol-4-yl)pyridine (3) and 2-(1,2,3-selenadiazol-4-yl)pyridine (4) with palladium(II), nickel(II), ruthenium(II), copper(II), and silver(I) reagents are reported. In general, these ligands chelate to the metal but are curiously prone to positional disorder in the X-ray crystal structures of their complexes. With silver tetrafluoroborate, ligand (3) forms an ordered M2L4 complex that contains an unsupported Ag–Ag interaction. Treatment of (4) with excess silver nitrate leads to an intriguing molecular rearrangement that produces a silver complex of 3-formyl-1,2,3-triazolo[1,5-a]pyridine.
