Eight novel SrII-LnIII heteronuclear coordination polymers based on pyridine-2,6-dicarboxylic acid (H2pda) and imidazole (im) ligands, namely, [LnSr(pda)3(H2O) 5]·Him·H2O (Ln = Eu (1), Gd (2), Tb (3)), [Ln2Sr(pda)6(H2O)5] ·4Him·C2H5OH·nH2O (Ln = Eu (4), n = 5; Gd (5), n = 4), [LnSr(pda)3(H2O) 4]·Him·3H2O (Ln = Gd (6), Tb (7)), and [GdSr(pda)3(H2O)5]·Him·C 2H5OH·3H2O (8), have been prepared by employing different amounts of imidazole. X-ray crystal structure analysis reveals that these compounds exhibit a rich structural chemistry. Complexes 1-3 possess 2-D frameworks. Complexes 4-5, 6-7, and 8 exhibit three types of 1-D chain structure. The structures of the complexes could be rationally tuned via adding different amounts of imidazole. The luminescent properties of these complexes have been investigated. The results show that EuIII and TbIII complexes exhibit intense red and green luminescence emission which are characteristics of TbIII and EuIII, respectively. Solid-state quantum yield and the lifetime of these complexes are also reported.
