摘要
The use of the 2-pyridyl oxime ligands (LH) 2-pyridinealdoxime, methyl 2-pyridyl ketone oxime and phenyl 2-pyridyl ketone oxime in Co chemistry has been investigated and led to two families of compounds. The first family includes the mononuclear octahedral, low-spin complexes [Co-II(L)(3)], while the second family consists of the trinuclear, mixed-valent linear clusters [(Co2CoII)-Co-III(L)(6)]X-2 (X = ClO4-, PF6-). The latter are prepared by the reactions of the former with an appropriate Con source. The structural, physical and spectroscopic properties of the complexes are described. (C) 2008 Elsevier Ltd.
