Three coordination polymers were obtained through solvothermal synthesis based on 4-(pyridin-3-yl) benzoate with Zn(II), Cd(II) and Mn(II) ions, respectively. Complex 1 possesses 1D zigzag chain composed by tetrahedral Zn(II) ions and mu-OH, which is further connected to four adjacent chains through 4-(pyridin-3-yl) benzoate, resulting in a dia net. While complexes 2 and 3 are isomorphous, in which binuclear clusters of octahedral Cd (II)/Mn (II) bridged by mu-OH2 are extended through the 4-(pyridin-3-yl) benzoate to four adjacent clusters into a dia net. The luminescence properties of complexes 1 and 2 were characterized. Magnetic measurements of complex 3 indicate there are antiferromagnetic exchange between the two high-spin Mn(II) ions and spin-flop behavior.
