[Display omitted] •Synthesis and characterization of a trans-coordinating ligand including one pyridine and one imidazole moiety.•NMR studies of silver(I) and palladium(II) coordination by the pyridyl-imidazolyl ligand.•X-ray structural characterization of linear coordination of Ag(I) and trans-coordination of Pd(II). We describe the design, synthesis and characterization of the ligand, 4-[(2-imidazylethynyl)]-5-(2-pyridylethynyl)veratrole as well its coordination complexes with silver(I) and palladium(II). 1H NMR titration clearly indicates that 1:1 coordination complexes are formed with both cations. The X-ray structure of the palladium dichloride complex confirms the trans coordination of palladium(II) and the silver trifluoromethanesulfonate complex confirms the linear coordination geometry about silver(I).
