A dimeric complex of trivalent europium [Eu 2 Cl 4 (bc) 2 (ptpy) 2 ] ( 1 ), containing the separate ligands 4'‐phenyl‐2,2':6',2''‐terpyridine (ptpy) and benzoate (bc – ) and a one‐dimensional double strand coordination polymer of the composition 1 ∞ [EuCl 2 (cptpy)] ( 2 ) with 4‐[2,2':6',2''‐terpyridin]‐4'‐yl‐benzoate (cptpy – ) were obtained. The products exhibit structural similarities despite the character of joint and separate functionality of the ligands. The dimer 1 shows photoluminescence with high quantum yield [61(2) %]. Eu 3+ emission lifetime is 1.493(1) ms at room temperature and rises to 1.649(1) ms upon cooling to 77 K.
