All these complexes were characterized by elemental analyses (C, H, N), FT-IR, thermogravimetric analysis (TGA), powder XRD and single crystal X-ray crystallography. They are formulated as [Cu(2-OHNA)2] 1, [Cu(6-OHNA)2(μ-H2O)2]n 2 and [Cd(6-OHNA)2(μ-H2O)2]n 3. Complex 1 is mononuclear 0D square planar complex which extends its dimensionality by weak supramolecular interactions such as π–π stacking interactions and intermolecular hydrogen bonding. Complexes 2 and 3 are polymeric aqua-bridged 1D infinite chain of Cu(II) and Cd(II), respectively. The central metal ions in these two complexes are in octahedral coordination environment. These two complexes are also assembled by π–π stacking interactions, inter- and intramolecular hydrogen bonding interactions. 10a2-Hydroxynicotinic Acid10a6-Hydroxynicotinic Acid10aCoordination polymer10aPolymeric Aqua-Bridged10aX-ray diffraction1 aSingh, S.K.1 aSrivastava, K.1 aBanerjee, R.1 aPrasad, J.  uhttps://library.ncl.res.in/content/syntheses-and-single-crystal-x-ray-diffraction-studies-hydroxynicotinic-acid-based-complexes
