Abstract: | In the title compound, In(C8H4O4)(OH)(H2O)]n, the coordination of the InIII ion is composed of six O atoms from three dianionic benzene‐1,2‐dicarboxylate ligands, two hydroxyl groups and one coordinated water molecule in a distorted octahedral geometry. The In3+ ions are linked by the hydroxyl groups to form zigzag In–OH–In chains, which are further bridged by the benzene‐1,2‐dicarboxylic acid ligands to generate a two‐dimensional layered structure featuring three types of rings (six‐, 14‐ and 20‐membered). Hydrogen bonds between the water molecule and a carboxylate O atom, and between the hydroxyl group and a carboxylate O atom, are observed within the layers. In the crystal packing, there are π–π stacking interactions between the benzene rings of adjacent layers, with a centroid‐to‐centroid distance of 3.668 (3) Å and a dihedral angle of 4.8 (2)°. |
