关 键 词：Spin-crossover π radical anion transition temperatures
摘 要：Transition metal complexes having d4-d7 electron counts in first-row are typically observed spin *** of the molecular bistability of spin-crossover,there is enormous interest for applications such as molecular switch,sensorsand digital memory.1 We systhesised a bis（α-iminopyridine）metal iodine complexes2（Scheme 1）.This complex consists of a neutralα-iminopyridine and a reducedπradical anion.A spin transition occurs at the temperature of ***-temperature single-crystal X-ray diffraction revealed that the S=1 to S=2 transition is associated with an increase in the Fe-N bond distances.
