合成了Fe[(Htrz)~9~/~4(NH~2trz)~3~/~4](BF~4)~2.H~2O(1)和Fe[(Htrz)~3~/~2(NH~2trz)](BF~4).3H~2O(2)两个"分子合金"类自旋转换配合物。其变温光谱表明,它们在室温附近具有自旋转换行为,同时还伴有热致变色及滞后现象。

Two new molecular alloys, the Fe[(Htrz)~9~/~4(NH~2trz)~3~/~4](BF~4) ~2.H~2O(1) and Fe[(Htrz)~3~/~2(NH~2trz)](BF~4).3H~2O(2), are synthesized and investigated by optical measurements (where Htrz stands for 4-H-1, 2, 4-triazole; NH~2trz for 4-NH~2-1, 2, 4-triazole) . Complexes 1 and 2 show spin transitions with hysteresis and thermochromism in the close vicinity of room temperature.

Key words: IRON COMPLEX, THERMOCHROMISM
