We synthesized a novel phenanthroline-based mononuclear Fe(II) compound [Fe(TTD) 2 (NCS) 2 ]⋅CH 3 CN ( 1 , TTD = 1,4,8,9-tetraaza-triphenylene-2,3-dicarbonitrile). And its crystal structure, optical and magnetic properties were analyzed. The thermally induced SCO of the compound is a one-step abrupt transition. In addition, light can also control the spin state of the compound. By using 660 nm light-excited compound, LIESST (light-induced excited spin-state trapping) effect can be achieved.
