Pressure effect investigations on the magnetic behaviour of the 3D SCO polymers {Fe(3CN-py)(2)[Ag(CN)(2)](2)} (.) 2/3H(2)O (1) and {Fe(3CN-py)(2)[Au(CN)(2)](2)} (.) 2/3H(2)O (2) have been carried out in the range of 10(5) Pa to 0.7 GPa. Despite both compounds are isostructural their magnetic behaviour under applied hydrostatic pressures is very different. Strong nonlinearity in the T-c(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. (c) 2006 Elsevier B.V. All rights reserved.
