Compounds based on the [Zn(hydet-en)(2)].(tpht).(H2O) (1) (tpht= dianion of terephthalic acid, hydet-en= N-(2-hydroxyethyl) ethylenediamine) has been synthesized which is characterized by single crystal X-ray determination, IR and thermal analysis. In 1, the Zinc(II) ion is six-coordinated that sandwiched by two hydet-en ligands which lies each hydeten ligand adopts a tripodal conformation and acts as tridentate ligand, carboxylate is uncoordinated. The coordination monomer is connected by C(13) chains and linear chains are connected by O-H center dot center dot center dot O H-bonds formed by DA: AD type organization of aqua ligands and tpa2-ions resulting in R-4(4); synthons to 3D structure. The FT-IR investigation of the complex were performed within the mid-IR region, mainly focusing on the characteristic vibrations of its free state and ligand behaviour in the case of complex formation. Thermal behaviours of 1 were followed using TG, DTA and DTG techniques.
