摘要：
Hexacoordinated Co(III) complexes bearing three C,O-bidentate ligands (9a and 9b) were prepared from 1-bromo-2-(P-tolyloxymethyl)benzene (8a) and 1-bromo-2,6-bis(p-tolyloxymethyi)benzene (8b), respectively. Both complexes were stable in air at room temperature. X-ray analyses revealed that the structures of both complexes were essentially the same. According to variable temperature H-1 NMR study, it was found that the two oxygen ligands on the same aromatic ring of 9b interchanged with each other. (c) 2006 Elsevier B.V. All rights reserved.
