| Research Abstract |
Quasi-one-dimensional metal complex has been attracting much attention because they show physical properties. All of the Ni compounds and Pd and Pt compounds form MH and CDW states, respectively, without exception. In the our former research, we have succeeded in realizing Pd (III) MH state. In this study, we measured ^<15>N-NMR spectra and succeeded in observing that CDW amplitude gradually decreased with decreasing temperaure for the first time. In addition, we tried to realize Pt (III) MH state by introducing long alkyl chains into iodo-bridged Pt compounds. As a result, we have clarified that Pt-Pt distance is gradually decreased with longing alkyl chain length.
