A new Mn(II) complex [Mn(H2O)(L)(Phen)(2)]center dot(H2O)(3) (1) with 2,2'-bipyridine-3,3'-dicarboxylic acid (H2L) and 1,10-Phenanthroline (Phen) as ligands has been synthesized. Crystal data for 1 are as follows: monoclinic, space group P2(1)/c. In 1, the central Mn(II) ion is located in a distorted octahedral coordination environment. The magnetic, fluorescence and electrochemical properties of 1 are studied. The results show that 1 has weak antiferromagnetic property at low temperatures, and when the exciting radiation is set at 656 nm, 1 can give off one broad emission band at around 682 n...

以2,2’-联吡啶-3,3’-二羧酸(H2L)和1,10-邻菲啰啉(Phen)为配体合成了一个新的锰(Ⅱ)配合物[Mn(H2O)(L)(Phen)2]· (H2O)3.该配合物晶体属单斜晶系,空间群P21/c.在配合物中,中心锰(Ⅱ)离子的配位数是6,处于变形的八面体配位环境中.还测定了标题配合物的磁性,荧光和电化学性能,结果表明:在低温下,配合物有反铁磁性；当激发波长为656 nm时,配合物在682 nm附近有一个宽的荧光发射峰;在循环伏安过程中配合物的电子转移是准可逆的,对应的电极反应是Mn(Ⅲ)/Mn(Ⅱ).
