Metal-organic frameworks (short: MOF) are a relatively new class of crystalline materials with a nanoporous structure. MOFs consist of metal coordination centres and organic linkers forming a three dimensional pore system with prospective applications in heterogeneous catalysis, separation and gas processing. In this study we investigate the host-guest interaction of MOF-5 (Zn_{4}O(bdc)_{3}) loaded with ferrocene (FeC_{10}H_{10}) via two-dimensional MAS NMR and PFG NMR techniques. In agreement with computer simulations, we found that the adsorbed ferrocene molecules are located close to the carbon rings of the organic linkers of the MOF-5 lattice. Additional the self-diffusion-coefficient were measured and compared with results of MD simulations.
