The use of pyridine-2,4-dicarboxylic acid (H2pydc) in the construction of SrII and SrII-MII(M=Co, Ni, Zn and Cu) coordination polymers is reported. Eight complexes, that is, [Sr(pydc)H2O]n(1), [MSr(pydc)2(H2O)2]n (M=Co (2), Ni (3), Zn (4)), [ZnSr(pydc)2(H2O)7]n·4nH2O (5), [SrCu(pydc)2]n (6), [SrCu(- pydc)2(H2O)3]n·2nH2O (7), and [Cu3Sr2(pydc)4(Hpydc)2(H2O)2]n (8), have been synthesized via dexterously choosing the appropriate strontium sources and transition metal salts, and rationally controlling the temperature of the reaction systems. Complexes 1, 2 (3, 4), 6, and 8 display four types of 3- D framework structures. Complexes 5 and 7 exhibit a 2-D network and a 1-D chain structure, respectively. The 2-D complex 7 can be reversibly transformed into 3-D compound 6 through temperature-induced solvent-mediated structural transformation. The luminescent property studies indicated that complex 1 shows a strong purple luminescent emission and 4 exhibits a strong violet luminescence emission. The magnetic properties of 2, 3, and 8 were also studied. Antiferromagnetic MII···MII interactions were determined for these complexes.
