X-ray-induced phase transitions by selective excitation of heterometal ions in a cyanide-bridged Fe-Co molecular square

摘要

A cyanide-bridged tetranuclear Fe-Co complex showed electron-transfer-coupled spin transitions induced by X-ray irradiation. Single crystal X-ray diffraction measurements and X-ray absorption spectro-scopy revealed that the X-ray-induced phase transition ratio was significantly altered by the selective excitation of the metal ions.
