Outline of Final Research Achievements |
We have succeeded in synthesizing the novel Pd-Br chain compound with averaged valence state which is stable up to 400 K. We measured physical properties of this compound. This compound showed extremely high electrical conductivity (40 Scm-1at room temperature), which is 10^6 higher than previous Pd-Br compound. The averaged valence state was stable up to 443 K(decomposition temperature). Such a stable averaged valence state has not been shown in the previous Pd-Br chains. This is because hydrogen bond between hydroxy group of the dabdOH ligand and Br- ion made 1D chains far away each other, and resultantly compression of 1D chain direction occured. We also measured thermoelectoric property of a series of MX chain compounds. We measured [Ni1-xCox(chxn)2Br]Br2. The pure [Ni(chxn)2Br]Br2 showed negative Seebeck efficient, whereas the absolute value of that decreased with increasing Co ratio.
