Metal Complexes of meso–meso Linked Corrole Dimers

Cobalt,
gallium, silver, and copper complexes of 5,5′-linked corrole
dimer 1 and 10,10′-linked corrole dimer 2 were synthesized by metalations with Co­(OAc)2·4H2O, GaCl3, AgOAc, and Cu­(OAc)2·H2O, respectively, in good yields. The structures
of cobalt­(III), gallium­(III), and silver­(III) complexes have been
unambiguously revealed by X-ray diffraction analysis. Their optical
and electrochemical properties have been studied, which revealed different
electronic interactions between the two corrole units depending upon
the positions of meso–meso linkage and axial-ligand
coordination modes.

通过金属化反应，分别以 Co(OAc)2·4H2O、GaCl3、AgOAc 和 Cu(OAc)2·H2O 为金属源，合成了 5,5'-连接的腐胺二聚体 1 和 10,10'-连接的腐胺二聚体 2 的钴、镓、银和铜络合物，产率颇高。通过 X 射线衍射分析，钴(III)、镓(III)和银(III)络合物的结构得到了明确的揭示。对其光学和电化学性质的研究揭示了两个腐胺单元之间的电子相互作用因中位-中位连接和轴向配位模式的位置不同而存在差异。
