Three In(III) MOFs based on diphenic acid and nitrogen-donor ancillary ligands were obtained as pure phases. Two of them have 1D chain structures, and the third forms 2D zig-zag layers. The different torsion angles adopted by the diphenic ligand along with the existence of several non-covalent interactions govern the crystal packing and determine the formation of a centrosymmetric one-dimensional compound (1) or a non-centrosymmetric helical chain-based compound (3). Reaction with 2,2′-bipyridyl under certain conditions leads also to the formation of two dimeric precursors (compounds 4 and 5). The topological study of all their nets is reported.
