Magnetic Resonance Behavior and Metal-Metal Interactions in Bimetallic Complexes of Pyridylmethylketazine

This study is on the NMR proton relaxation rates and metal-metal interactions of MM$\sp\prime$(PMK)$\sb{3}$(NO)$\sb3)\sb{4}\cdot{\rm xH\sb{2}O,}$ where M and M$\sp\prime$ are Co(II), Ni(II), Cu(II), and Zn(II), and PMK (pyridylmethylketazine) is the condensation of two molecules of 2-acetylpyridine with hydrazine. Gatteschi and co-workers obtained interesting proton NMR results on such complexes; they found the normally broad peaks of the Cu(II) and Ni(II) complexes to become much sharper when Co(II) was also in the complex. Because of their results, work was done here to determine the proton relaxation rates, their implications for the electron relaxation rates, and the amount of interaction needed between the ions for this behavior to occur. Among the studies were proton T$\sb{1}$ measurements, EPR spectra, and variable temperature magnetic susceptibility determinations.
