The novel centrosymmetric complex, [In2(pydc)2(pydcH)2(H2O)2] • 2H2O (1), (pydcH2 = 2,3-pyridinedicarboxylic acid) was synthesized and thoroughly characterized using elemental analysis, IR, 1H NMR spectroscopy and single crystal X-ray diffraction. All of obtained data via routine methods are in agreement with single crystal X-ray diffraction information. Compound 1 crystallized in the triclinic system with space group Pī with two molecules per unit cell. Each In(III) is six-coordinated with InN2O4 bound set as distorted octahedral geometry. PydcH2 with capability hydrogen donating and versatile coordination mode appears in this complex as both mono depronotaed, bidenated ligand and doubly protonated-tridentate one. Each tridentate ligands is coordinated to In(III) through two O atoms and one N atom and play as bridged role between two In(III) ions. The distance between two In(III) is about 6.527 Å and size of resultant hole within binuclear complex is around 3.195×5.567Å2. In the title compound, different types of hydrogen bonds and electrostatic interaction play important roles in stabilizing the corresponding lattice and assemble to 3-D supramoleculer network.
