We measured the Raman, UV-visible and 13C CP-MAS NMR spectra of halogen-bridged 1-D Cu-Pt mixed-metal complexes, [Cu(chxn)2][PtX2(chxn)2]X4 (X: Cl and Br), consisting of -X-Cu-X-Pt-X-chain. The Raman spectra showed an overtone progression of symmetric stretching mode of Pt(IV) -Cl atoms and the fine structures with halogen isotopic splitting in Pt-Cl band below ca. 50 K. The broad carbon signals of the 13C NMR spectra observed at room temperature are attributable to strong paramagnetic effect from Cu(II) sites. This result is supported by the weak antiferromagnetic interactions between Cu(II) sites in the chain.

We studied comparison of high school education between Myanmar and Japan by using the textbooks of chemistry in high school, visiting schools and study tours. In both countries, the level of curriculum contents common. The contents of the textbooks are arranged systematically in order to the laws, principles, basic concepts, examples and explanations. There is a little difference in the explanation of each topic, some are details in Myanmar, but some are details in Japan. School chemistry can teach the students about the influence of chemical knowledge on human society.

31P MAS NMR spectra were measured on -X-Pt-Pt-X-Pt-Pt-X- type complexes, A4[Pt2X(P2O5H2)4]・nH2O(A: K, NH4, Cs; X: Cl, Br, I). In these complexes, two kinds of 31P resonance lines observed at δ=50-70 and 20-40 ppm, whose values are close to those in the monomer Pt2+ and Pt3+ complexes, respectively. From the analyses of spectra and spin-lattice relaxation times T1, a mixed-valence -X-Pt2+-Pt2+-X-Pt3+-Pt3+-X- structure was concluded for K4[Pt2Cl(P2O5H2)4]・nH2O, (NH4)4[Pt2X(P2O5H2)4]・nH2O and Cs4[Pt2X(P2O5H2)4].

　概要を見る

IR and 13C NMR measurements in hetero-metal complexes, [Pd(en)2][PtX2(en)2] (NO3)4 (X: Cl, Br) afforded two kinds of signals assignable to Pd and Pt moieties, indicating the formation of the Pd(II)-X-Pt(IV)-X-type chain structure. Weak ESR signal observed in [Pt(en)2][PtCl2(en)2] (NO3)4 suggested the formation of only small amounts of spin soliton.
