Charge-Density-Wave to Mott—Hubbard Phase Transition in Quasi-One-Dimensional Bromo-Bridged Pd Compounds.
A -Pd-Br-Pd- Mott-Hubbard state was observed in a quasi-one-dimensional bromo-bridged Pd compound [Pd(en)Br](C-Y)·HO (en = ethylenediamine, C-Y = dipentylsulfosuccinate) for the first time. The phase transition between Mott-Hubbard and charge-density-wave states occurred at 206 ± 2 K and was confirm...

The phase transition between Mott-Hubbard and charge-density-wave states occurred at 206 ± 2 K and was confirmed by using X-ray, ESR, Raman and electronic spectroscopies, electrical resistivity, and heat capacity. From X-ray powder diffraction patterns and Raman spectra of a series of Pd-Br compounds, [Pd(en)Br](C-Y)·HO (n = 4,5,6,7,8,9, and 12), chemical pressure from the alkyl chains of the counterions caused the phase transition. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2008 holdings: @attributes: islocal: N |
