Two coordination polymers, namely, [Ni(L)(CHN)(HO)] ( 1), and [Mn(L)(HO)] ( 2) have been hydro(solvo)thermally synthesized through the reaction of 4-(4-hydroxypyridinium-1-yl)phthalic acid (HL) with divalent nickel and manganese salts. As a result of various coordination modes of the versatile 4-(4-hydroxypyridinium-1-yl)phthalic acid, these compounds exhibit structural diversity. Complex 1 exhibits a 3D coordination framework through the rich hydrogen bond. Complex 2 exhibits a 3D coordination network based on layers. These complexes have been characterized by powder X-ray diffractions (PXRD), IR spectroscopy, elemental analysis, thermogravimetry, single-crystal X-ray crystallography and solid UV spectroscopy.
