Solid state nuclear magnetic resonance (NMR) spectroscopy was applied to two metalorganic frameworks (MOFs), MIL-101 (Cr) and NH2-MIL-101 (Cr), with the aim of investigating their interaction with water. The two MOFs contain coordinatively unsaturated Cr sites showing a strong affinity to water. Analysis of the NMR data allowed us to distinguish water bound to Cr3+ from unbound water residing in the porous space and to set a lower boundary to the residence time of water on the Cr site when the porous space is filled with water. This has implications on the adsorption behaviour of the porous matrix and influences the MOF performance in adsorption heat transformation.
