摘要：
The title polymer compound, [In(1,2-BDC)(μ₂-OH)(H₂O)]n (1) , (1,2-BDC=benzene-1,2- dicarboxylate) has been synthesized by a hydrothermal reaction using In₂(SO₄)₃．9H₂O, benzene-1,2- dicarboxylic acid and water at 423 K. The structure of 1 was characterized by elemental analysis, FT-IR and single-crystal X-ray diffraction. The asymmetric unit of compound 1 contains a six-coordinate In(Ⅲ) ion with a slightly distorted octahedral geometry, defined by six O atoms from one water molecules, three 1,2-BDC ligands and two hydroxyl ligands. Each 1,2-BDC ligand affords a three-connecting node. The In(Ⅲ) centers are interconnected through 1,2-BDC ligands to generate a two-dimensional layered structure. Classical O—H•••O hydrogen bonding is observed in the crystal structure. The crystal structure is further consolidated by π•••π stacking between nearly parallel aryl ring systems [dihedral angle = 1.1(2)°], the centroid•••centroid distance between aromatic rings of adjacent 1,2-BDC ligands being 3.671(3)Å. The crystal was found to be a racemic twin, and the flack parameter is 0.48(3).
