Abstract:
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.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
