Abstract: Porous coordination polymers have been the subject of intense study over the past ten years. The key feature of these materials is a robust framework that remains in tact upon desolvation – the potential uses of these materials range from gas storage to catalysis. The current work focuses on the magnetic behaviour of these frameworks; given the nature of the structures are often low dimensional and low density magnetic topologies and the possibility exists to incorporate frustration, the magnetic properties are often of interest in there own right. If these magnetic properties could be linked to the small changes in structure associated with desolvation, the potential exists for using these materials as magnetic sensors. The material which I will focus on in this contribution, Co3(OH)2(C4O4)2.3H2O, shows an unusual three phase magnetic behaviour due to a combination of single ion effects and magnetic frustration, of particular interest is a novel spin idle phase.1 Recently we have moved on from looking at this spin idle phase and have started to probe the incommensurate phase that proceeds it. Further we have started to study the effect of hydration on the magnetic behaviour. Previous work 2 has shown that there is a large effect on dehydration – with it being hypothesized that a switch from antiferromagnetic to ferromagnetic behaviour is observed. Our recent work has shown that although there is a very clear effect – it is due to small changes in the coordination sphere of the magnetic ion and not the hydrogen bonding pathway as previously suggested. The work has made use of a combination of both single crystal and powder neutron diffraction.
