Making use of the phenomenon of light-induced spin-crossover in the [Zn,\_xFe,(ptz)6] (BF& spin-crossover system, very high diffraction efficiencies 7 can be achieved in non-degenerate four-wave-mixing. In the mixed crystal with X= 0.1 and at 76 K, i.e. at a temperature where the system is predomina

At low temperatures an external pressure of 1 kbar accelerates the high-spin ~ low-spin relaxation in the [Znl\_xFex(ptz)6](BF4) 2, x = 0.1, spin-crossover system by one order of magnitude. This is due to the large difference in 0 3 volume between the high-spin and low-spin states of 26 A/molecule.
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
