Our minireview article has been recently featured on the front cover of Eur. J. Inorg. Chem.
On the front cover we show a 
selection of mixed‐addenda polyoxometalate structures, along with a hexametalate analogue used in the construction of metal organic frameworks. Isomerism of these mixed‐metal molecular metal oxides is highly complex, often incorporating a wide range of different metals and spanning homo‐ and heterogenous catalysis. Formal metal substitution enables the tuning of specific properties; however, this presents an isomer problem, which has been explored experimentally and computationally.
