第一过渡系金属M(Ⅱ)的联吡啶配合物电子光谱的研究——谱带归属、D_q、B、β、ζ_(3d)、λ

Studies on the Electronic Spectra of Tris-(2, 2'-bipyridine) and the First Row of Transition Metal (Ⅱ) Complexes

我们合成了[M(bpy)_3]X_p(X为SO_4^(2-)、Cl^-或ClO_4^-,P=1或2。M为V、Cr、Mn、Fe、Co,Ni、Cu、Zn)。测定了其电子光谱,指认了各谱带的归属,并预计了未能显示的谱带的位置。求得了八面体场的参数:D_q,Racah参数B、电子云扩展系数β、M的单电子的旋-轨偶合参数ζ3d和配合物的旋——轨偶合参数λ.指出了与[M(bpy)_3]^(2+)外的电子光谱相关的电子跃迁。

The tris-(bipyridine) complexes of the bivalent metal ions (except Sc, Ti) of the first row of transitiob element were synthesized and their electronic absorption spectra were investigated extensively. Some important parameters of Ligand Field Theory (LFT) D_q, B, β, ξ_(3d) and λ will be reported in this article.
