✦ Synopsis

II IS known that [Fe(Z-mephen),]

(C104)7 in the solid state IS an iron(H) spin-crossover system which shows light-induced excited spin state trapping (LIESST). The thermal spin-crossover behaviour of the complex [Fe(2-mephen)3]L+ embedded in various polymer matrices is similar to the solid-state behavlour, and a hght-induced long-lived excited state is observed at temperatures below SO K. Relaxation CUNCS show that polymer matrlces are not very homogeneous media.

Fe(ptz)6(BF4)2 (ptz = I-propyltetrazole) is an iron(H) spin-crossover system which shows light-Induced excited spin state trapping. In this paper we show that (a) the same phenomenon can also be observed in Zn, \_ rFeX(ptz)6(BF4)2 (x = 0.1) and is therefore basically a single-ion property, and (b) t
