This thesis details the design, synthesis and characterisation of metal-organic frameworks (MOFs), with particular interest in their gas storage properties. 23 novel MOFS were synthesised by solvothermal methods from transition and lanthanide metal cations and a range of pyridine-carboxylate ligands. Three new Cu MOFs, all based on a similar metal node were synthesised. One possessed a previously unreported topology and H2 storage that was comparable to similar Cu MOFs in the literature. Another possessed a very rare self-entangled topology and the third possessed a more common rutile topology; this series demonstrated how compounds based on similar building blocks can show structural diversity_ A series of isostructural lanthanide frameworks were synthesised. They exhibited N2. H2 and C02 storage with particularly high enthalpies of adsorption of CO2; these values were amongst some of the highest published in the literature. A range of MOFs based on the same ligand were synthesisd, they had different structures but possessed the same topology, once again showing how MOF structures can share features but ultimately be different from one another. This thesis demonstrates the structural diversity that can be achieved when using pyridine-carboxylate ligands in the synthesis of MOFs and the impact upon gas storage of the functional groups in the ligand.
