| Research Abstract |
Electronic states of quasi-one-dimensional halogen-bridged metal complexes, so called MX- or MMX-chains, have been studied by electron spin resonance (ESR) technique. Spin moments of palladium (III) are induced from the nonmagnetic state in the Ni-Pd mixed-metal complexes as determined from the spin susceptibility enhancement and g values. This result shows clear ligand molecule dependence. In the MMX-chain complexes having binary countercations, dehydration-induced reversible change of the electronic state has been demonstrated from the change of the ESR spectrum. Furthermore, thermal excitation of soliton has been observed in the dehydrated complexes.
