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.

准一维金属配合物由于其独特的物理性质而受到人们的广泛关注。所有的Ni化合物以及Pd和Pt化合物无一例外地分别形成MH和CDW态。在我们前期的研究中，我们已经成功地实现了Pd（III）的MH态。本研究首次测量了~ <15>1H-NMR谱，并成功地观察到CDW振幅随温度的降低而逐渐减小。此外，我们尝试通过在碘桥铂化合物中引入长烷基链来实现Pt（III）MH态。结果表明，随着烷基链长的增加，Pt-Pt距离逐渐减小。
