Abstract

A combined study of the high pressure crystallography and high pressure magnetism of the complex [Mn3(Hcht)2(bpy) 4](ClO4)3·Et2O·2MeCN (1·Et2O·2MeCN) (H3cht is cis,cis-1,3,5-cyclohexanetriol) is presented in an attempt to observe and correlate pressure induced changes in its structural and physical properties. At 0.16 GPa the complex 1·Et2O·2MeCN loses all associated solvent in the crystal lattice, becoming 1. At higher pressures structural distortions occur changing the distances between the metal centres and the bridging oxygen atoms making the magnetic exchange between the manganese ions weaker. No significant variations are observed in the Jahn-Teller axis of the only MnIII present in the structure. High pressure dc χMT plots display a gradual decrease in both the low temperature value and slope. Simulations show a decrease in J with increasing pressure although the ground state is preserved. Magnetisation data do not show any change in |D|. © The Royal Society of Chemistry 2009.
