A family of three new mononuclear complexes of the general form [Fe(Lpz)2(NCE)2] has been prepared (Lpz = 4-p-tolyl-3-(2-pyrazinyl)-5-(2-pyridyl)-1,2,4-triazole; E = S, Se, BH3). All three exhibit spin crossover, in two cases with hysteresis, with T1/2 being predictably tuned by varying the coordinated anion.
我们制备出了一般形式为[Fe(Lpz)2(NCE)2]的三个新单核配合物家族(Lpz = 4-对甲苯基-3-(2-吡嗪基)-5-(2-吡啶基)-1,2,4-三唑;E = S、Se、BH3)。所有这三种化合物都表现出自旋交叉,其中两种还存在滞后现象,T1/2 可通过改变配位阴离子进行调节。
