A new indium(III) coordination polymer [In(OH)(Hpdc)(H 2 O)] n ( 1 ) H 3 pdc = 3,5-pyrazole-dicarboxylic acid) has been synthesized under hydrothermal condition and characterized by the elemental analysis and single crystal X-ray diffraction. X-ray diffraction analysis reveals that 1 (C 5 H 5 InN 2 O 6 ) crystallizes in the monoclinic space group P 2 1 /n, and features an interesting 2D layer constructed by 1D In–Hpdc chains and μ 2 -OH ligands. Unit cell parameters for 1 : a  = 10.406(2), b  = 6.326(2), c  = 11.631(2) Å, β  = 104.0(1)°, and Z  = 4. Index Abstract The title compound, [In(OH)(Hpdc)(H 2 O)] n (H 3 pdc = 3,5-pyrazole-dicarboxylic acid), was synthesized under hydrothermal condition by the treatment of InCl 3 ·4H 2 O with 3,5-pyrazole-dicarboxylic acid and its crystal structure determined. Single crystal X-ray diffraction analysis reveals that the molecular structure of the title compound is an interesting 2D layer constructed by 1D In–Hpdc chains and μ 2-OH ligands.
