Three one‐dimensional coordination polymers, [MnCl 2 (4‐pyterpy)]∙2CHCl 3 ( 1 ), [Mn(NO 3 ) 2 (4‐pyterpy)]∙CHCl 3 ( 2 ) and [Ag(NO 3 )(3‐pyterpy)]∙H 2 O ( 3 ) (4‐pyterpy = 4′‐(4‐pyridyl)‐2,2′:6′,2″‐terpyridine and 3‐pyterpy = 4′‐(3‐pyridyl)‐2,2′:6′,2″‐terpyridine) were synthesized and characterized by X‐ray diffraction. All three compounds exhibit a rare “head‐to‐tail” coordination of the multidentate ligand, but differ significantly in their polymer chain conformations. Additionally, the fluorescent properties of all three compounds were investigated and show a weak, ligand‐centered fluorescence at 416–418 nm.
