| 摘要: 氨基多羧酸类配合物的配位数和结构不但与金属离子的半径、电荷和电子结构有关，而且还与氨基多羧酸类配体的形状和大小有关。本文报道了Na2［FeⅢ(ida)2］2·3H2O(ida=亚氨基二乙酸根)配合物的合成并测定了它的分子结构和晶体结构。具体结果如下：单斜晶系，P21/c空间群，a=15.6480(10)?,b=16.78 | |

| Abstract: In the present paper we described the synthesis and crystal structure determination of the title complex. The crystal structure of the title complex salt has been determined by single-crystal X-ray structure analysis. The crystal data are as follows; Monoclinic, P21/c, a=15.6480(10)?, b=16.7870(10)?, c=10.347(2)?, β=90.790(10)°, V=2717.7(6)?3, Z=3, and R=0.0333 for 4789 observed reflections. The complex anion has a pseudo-octahedral structure distorted more than the CrⅢ and CoⅢ analogs, in which each iminodiacetato ligand (ida) is coordinated in a facial fashion with the two N atoms in a cis configuration, resulting in an unsym-fac structure. | |
