2-Pyridyloximate clusters of cobalt and nickel

The use of 2-pyridyloximate(-1) ligands, (py)C(R)NO− [R = H, Ph, 2-pyridyl (py)] in cobalt and nickel(II) chemistry has been investigated and led to four families of clusters. A representative member of each family, namely [CoIICo2III{(py)C(ph)NO}6](PF6)2 (1), [Co2IICo2III(OH)2(O2CMe)2{(py)2CNO}4(MeOH)2](ClO4)2 (2), [Ni9(OH)4{(py)CHNO}10(H2O)8]{N(CN)2}3(ClO4) [3{N(CN)2}3(ClO4)] and [Ni4(O2CMe)4{(py)C(ph)NO}4(MeOH)2] (4) is briefly structurally and magnetically described.

The use of 2-pyridyloximes, (py)C(R)NOH, in reactions with Co(II) and Ni(II) sources has led to four families of structurally interesting complexes which have been magnetically characterized.Figure optionsDownload as PowerPoint slide
