Pressure Effect Studies on the 3D Spin Crossover System: {Fe(3CN-py)2[M(CN)2]2}·nH2O (n < 2/3, M = Ag(I), Au(I))

[EN] Pressure effect investigations on the magnetic behaviour of the 3D SCO polymers {Fe(3CN-py)2[Ag(CN)2]2} · 2/3H2O (1) and {Fe(3CN-py)2[Au(CN)2]2} · 2/3H2O (2) have been carried out in the range of 105 Pa to 0.7 GPa. Despite both compounds are isostructural their magnetic behaviour under applied hydrostatic pressures is very different. Strong nonlinearity in the Tc(P) vs. P plot has been observed for compound 1 a fact which contrasts with the almost linear dependence observed for each spin transition in 2. However, both compounds are extremely sensitive to the application of pressure as well as the Tc(P) vs. P plots denote.Financial support is acknowledged from the Spanish Ministerio de Educación y Ciencia (MEC) (CTQ 2004 03456/BQU) and from the Generalitat Valenciana for the Research Grant ACOMP06/048.
