Abstract

A -Pd^IIIBr-Pd^III- Mott-Hubbard state was observed in a quasi-one-dimensional bromo-bridged Pd compound [Pd(Bn)₂Br](C ₅-Y)₂·H₂O (en = ethylenediamine, C ₅-Y = dipentylsulfosuccinate) for the first time. 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)₂Br](C_n-Y)₂·H₂O (n = 4, 5, 6, 7, 8, 9, and 12), chemical pressure from the alkyl chains of the counterions caused the phase transition.
