This research deals with the investigation of the correlation between the structures of molecules and their magnetic properties as a function of pressure. To do so, different kinds of molecules have been chosen from single-molecules magnets, chains to small molecules. The variety of molecules is necessary to find the best candidates for high pressure X-ray crystallography and high pressure magnetic measurements. Bonds lengths and angles have been successfully altered by using high pressure without the complicating issues of chemical modifications. These structural changes produced a significant effect on the magnetic properties. A tilting of the Jahn-Teller axis in [Mn12O12(O2CCH2tBu)16(H2O)4].MeNO2.CH2Cl2 has been observed both structurally and magnetically. Modification of π–π interactions from edge to edge interaction to offset π–π stacking in [Gd(PhCOO)3(DMF)]n or a conversion from a CH–π interaction to a π–π interaction in [N(PhCH2)(CH2CH3)3]2[Fe2OCl6] are also reported.
