A family of alkaline earth organosulfonate coordination solids is reported. In contrast to more typical crystal engineering approaches, these solids are sustained by the assembly of building blocks that are coordinatively adaptable rather than rigid in their bonding preferences. The ligand, 4,5‐dihydroxybenzene‐1,3‐disulfonate, L, progressively evolves from a 0D, 1D, 2D, to a 3D microporous network with the Group II cations Mg 2+ , Ca 2+ , Sr 2+ , and Ba 2+ , (compounds 1 – 4 ), respectively. This trend in dimensionality can be explained by considering factors such as hard–soft acid–base principles and cation radii, a rationalization which follows salient crystal engineering principles. The selective gas sorption properties of the microporous 3D network [Ba(L)(H 2 O)] ⋅ H 2 O, 4 , with different gaseous guests are also presented.
