X-ray K-absorption edge analysis of nickel in some nickel complexes of isonitrosoketones has been carried out using a 400-mm bent crystal spectrometer. The analysis has been used to deduce information regarding the mode of bonding, the magnetic behaviour and the coordination of Ni in the complexes. On the basis of the results obtained, it has been concluded that Ni ions in Ni(HMAO)2; have square planar structure whereas Ni ions in Ni(HTGA)2 have tetrahedral structure. On the other hand Ni ions in Ni(EINA)2; and Ni(INACA)2, are surrounded by octahedra. Ni ions in Ni(INACA)2 are in the valence state higher than two and appear to be paramagnetic. |
