英文摘要	Herein, we investigate the spin transition properties in a series of mononuclear Fe(II) complexes constructed by two pybox ligands and four counter anions. 1(BF4) undergoes an abrupt spin-transition at around 150 K, which proceeds to 50% completeness and is accompanied by a structural phase transition. 1(BPh4)center dot MeCN, 2(ClO4), and 2(BF4) all display gradual and complete SCO behaviours around or above ambient temperature. The desolvated compound 1(BPh4) exhibits a gradual but incomplete SCO center dot 2(PF6)center dot MeCN, 2(PF6) and 2(BPh4) show a two-step SCO. The well-defined two-step SCO of 2(BPh4) takes place at 100-200 K (T-1/2 = 150 K) and 400-500 K (T-1/2 = 446 K). In contrast, compounds 1(BF4)center dot MeCN, 1(PF6)center dot MeCN center dot Et2O and 1(PF6) remain high-spin at the measured temperatures. The LIESST (light induced excited spin state trapping) effect of several SCO compounds are also investigated, which display photo-conversion during light irradiation at low temperature at a relatively high level. Our results demonstrate that the [Fe(pybo(x))(2)](2+) series of complexes will become a new versatile system in spin-crossover research.; NSFC [21302035, 21371043, 21421005, 21322103, 91422302]; Fundamental Research Funds for the Central Universities; SCI(E); ARTICLE; yyzhu@hfut.edu.cn; liutao@dlut.edu.cn; 12; 1624-1636; 3
