In this new Dalton Transactions Hot Article, Cheetham et al. use neutron powder diffraction to examine the crystal and magnetic structure of some transition metal gallates.  The team accurately determined the locations of the hydrogen atoms to gain an insight into  how the different valences are accommodated as well as getting details about their magnetic structures.

MOFs have been the focus of extensive research due to their wide variety of intriguing structures and properties.  Most of the effort has focused on their gas adsorption and catalytic capabilities.  Dense frameworks, with extended inorganic connectivity (e.g. metal–oxygen–metal), have also recieved attention recently. These materials can exhibit properties (electrical conductivity and ferromagnetism)that are associated with purely inorganic compounds, such as metal oxides.
