摘　　要：研究了新近合成的马莱腈二硫纶·邻菲咯啉 - 5,6-二酮合锌配合物 Zn( mnt) ( phen- 5,6-dione) ( mnt2 - :1 ,2 - dicyano- 1 ,2 - ethylenedithiolate or maleonitriledithiolate;phen- 5,6- dione:1 ,1 0 - phenanthroline- 5,6- dione)的电子吸收光谱 ,探讨了马莱腈二硫纶·邻菲咯啉 - 5,6-二酮合锌配合物配体间荷移跃迁 ( L L′ CT)特性 ,发现该跃迁吸收谱带较 M( mnt) ( phen- 5,6-dione) ( M2 + :Fe2 + ,Co2 + ,Ni2 + ,Cu2 + …… )的 L L′ CT较弱 ,其本质是 Zn( mnt) ( phen- 5,6-dione)分子轨道能级图中 LL′ CT是宇称禁阻跃迁 .The electronic absorption spectra of complex Zn(mnt)(phen 5,6 dione)(mnt 2- :1,2 dicyano 1,2 ethylenedithiolate or maleonitriledithiolate;phen 5,6 dione:1,10 phenanthroline 5,6 dione)is reported in detail.The ligand to ligand charge transfer(LL′CT) characteristics of the title complex is emphatically investigated.The LL′CT band of the title complex is weaker by comparison with M(S S)(N N)complexes.The absorption band in the visible region of Zn(mnt)(phen 5,6 dione)that involves LL′CT from the dithiolate to the diimine(7b 2 to 7b 1) is symmetry forbidden.
