Magnetic superexchange is strongly dependant on the degree of orbital overlap and hence the interatomic distances and angles within a structure. One way of tuning magnetic interactions within a material is by the application of pressure, which can modify the interatomic distances and angles within the crystal structure. We propose to study the structural modifications of the quasi two-dimensional antiferromagnet, Cu(5CAP)2Br4 under the application of pressure, to investigate the changes in the dimensionality of the system and the modification of the hydrogen bonding network.
