摘要：

The first series of heterometallic Sr-II-M-II (M = Cu, Co, Ni and Zn) coordination polymers based on pyridine-2,5-dicarboxylic acid (H(2)pydc) are reported. Eight complexes of compositions, [Sr(pydc)(H2O)](n) (1), [CuSr(pydc)(2)(H2O)(4)](n) (2), [CoSr(pydc)(2)(H2O)(6)](2n)center dot H2O (3), [NiSr(pydc)(2)(H2O)(4)](n)center dot 3nH(2)O (4), [Sr(H2O)(6)](n)center dot n[Ni(pydc)(2)(H2O)(2)]center dot 2nH(2)O (5), [NiSr2(pydc)(3)(H2O)(8)](n)center dot 2nH(2)O (6), [ZnSr(pydc)(2)(H2O)(5)](n) (7) and [ZnSr2(pydc)(3)(H2O)(10)](n)center dot 2nH(2)O (8), have been prepared and characterized. The structures of the complexes could be controlled via rationally choosing the appropriate metal salts, adding the starting materials in different orders, and tuning the ratio of the starting materials. Eight varieties of structures, ranging from 1-D chains to 3-D networks, were obtained. The magnetic properties of 2, 3 and 6 were investigated from 2 K to 300 K. Antiferromagnetic M-II center dot center dot center dot M-II interactions were found for 2 and 6, and ferromagnetic interactions were determined for 3. The solid state luminescent properties of 1, 7 and 8 were also studied.
