The use of 4,4′‐[oxalylbis(azanediyl)]bis(2‐hydroxybenzoic acid) (H 6 L 1 ) in the Ba 2+ chemistry has afforded a 3D polymer, namely [Ba(H 2 L 2 )(H 2 O)] n ( 1 ), which is based on H 2 L 2 2– anions derived by the in‐situ metal‐assisted transformation of H 6 L 1 . The neutral H 4 L 2 [4‐(carboxyformamido)‐2‐hydroxybenzoic acid] ligand was isolated from 1 and characterized by spectroscopic methods. Polymer 1 is based on edge and face‐sharing BaO 10 polyhedra which create an inorganic layer pillared to the third dimension by the organic ligands and has been classified as an I 2 O 1 framework. The topological analysis of 1 provided an opportunity to introduce a method for the deconstruction of I 2 O 1 frameworks by adopting principles applied in the deconstruction of Metal‐Organic‐Frameworks (MOFs) with rod Secondary Building Units (SBUs). A detailed discussion and insights for the proper use of the I m O n notation which finds application in describing the dimensionality in MOFs, is also provided.
