  number of studies on the boundary between class II and III materials of the Robin–Day classification, there are few studies of compounds at the boundary between classes I and II. In this study, we synthesized a series of Pt- and Pd- MX-chain compounds with perrhenate counterions, [M(en)2][M(en)2X2](ReO4)4 (X = Br for M = Pd and X = Cl, Br, and I for M = Pt). All compounds were isostructural, and the metal–metal

  MX链已被广泛研究为一维混合价系统。尽管对Robin-Day分类的II类和III类材料之间的边界进行了大量研究，但在I类和II类之间的边界上对化合物的研究却很少。在这项研究中，我们合成了一系列具有高r酸抗衡离子[M（en）2 ] [M（en）2 X 2 ]（ReO 4）4的Pt和Pd- MX链化合物（对于M = Pd和X = Cl，Br和I，M = Pt）。所有化合物都是同构的，链中的金属-金属距离超过6Å，这是迄今为止报道的MX链化合物中最长的。对于[Pt（en）2 ] [Pt（en）2 Cl 2]（ReO 4）4（PtCl），在335 nm（3.7 eV）的UV区观察到间隔电荷转移（IVCT）跃迁，这是迄今为止报道的MX链化合物的最短波长，表明PtCl是我所限制的Robin-Day课程中最接近的课程。

  Temperature-and pressure-induced transitions from the charge-density-wave (CDW) phase to the Mott-Hubbard (MH) phase in the quasi-one-dimensional Br-bridged Pd compound, [Pd(en)(2)Br](C-n-Y)(2)center dot H2O (n = 4-9, and 12) (en: ethylenediamine, C-n-Y: dialkyl-sulfosuccinate), were investigated by means of crystal-structure analyses and Raman spectroscopy. From the systematic evaluations of the bridging-bromine displacements delta reflecting the CDW amplitudes, the distance L between the neighboring two Pd ions, and the Raman frequency omega(S) of the symmetric Pd-Br stretching mode, we demonstrated that omega(S) is a good measure of the CDW amplitude. By scrutinizing the variations of omega(S) in the pressure-induced and the temperature-induced CDW-to-MH transitions, we discuss the nature of the CDW-to-MH transitions in this category of materials.
