Abstract

Abstract : Unusual clustering of lanthanide-corrole units has been found in the first reported examples of anion-capped lanthanide corrole complexes, and the degree of aggregation can be controlled by the choice of the capping ligand. Abstract : The first synthesis of anion capped cerium corrole complexes is reported. Unusual clustering of the lanthanide corrole units has been found and the degree of aggregation can be controlled by the choice of the capping ligand. A polymeric structure1a, with the general formula [Cor–Ce(THF)–Cp–Na] n (Cor = 5, 15-bis(2, 4, 6-trimethylphenyl)-10-(4 methoxyphenyl)-corrole, THF = tetrahydrofuran), is formed using sodium cyclopentadienide (NaCp) and a dimeric structure2a, with the general formula [Cor–Ce–Tp]2, is formed when potassium tris(pyrazolyl)borate (KTp) is used. Encapsulation of the counter-cation leads to the isolation of the monomeric structures1b and2b, with the general formulas [AM(2.2.2-cryptand)][Cor–Cp–X] (AM = Na or K, X = Cp or Tp). The structural and spectroscopic properties of the complexes have been investigated.
