The indium compound (ref. 26) is an example for a different oxidation state (+3) being accommodated by a more complex organic counterpart. In this specific case, a delicate combination of structure-directing agents was used: the unit cell contains 4,5-imidazoledicarboxylate (Himdc) linkers, protonated amines balancing the charges, and three different solvents.26 All this complexity is identified and reduced by our approach, transforming the structure to its fundamental AB2 network.
