THE SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF THE NEW DITHIOPHOSPHINIC ACID Ni(II) COMPLEX Hakan Dal,a Ertuğrul Gazi Sağlam,b Berline Mougang-Soumé,c Tuncer Hökelekd a Department of Chemistry, Anadolu University,26470 Yenibağlar, Eskişehir, Turkey b Department of Chemistry, Bozok University, 66900, Yozgat, Turkey c Department of Chemistry, Université de Montréal, Montréal, Québec, Canada d Department of Physics, Hacettepe University,06800 Beytepe, Ankara, Turkey [email protected] Organodithiophosphinic acids have a highly selective complexing tendency towards soft acid type metal cations [1]. Reducing ability of DTPAs make them a suitable antioxiditive additive for lubricating oils [2]. These acids have also been found to be efficient pesticides [3]. Their antibacterial and antifungal activities make them potential curing agents in the treatment of some chronic lung disease [4]. Some DTPA have succesfully been used as a synergistic additive to cephalosporin-type antibiotics [5]. In recent years, they have been reported to be used as potential extracting agents for various metals in lanthanide and actinite samples [6]. In this study, DTPA ligands were prepared through the reaction of Lawesson Reagent (LR) and Grignard compounds. Acid so obtained was treated directly with Nickel (II) salt, and the complex ([Ni(L)2] was found to be crystalizable in acid media. The structure of the compound was elucidated by elemental analysis, 1H-,13C{1H}-, 31P{1H}- NMR; and also by MS-, FTIR- and RAMAN spectroscopies. The solid state structure of the novel nickel complex was characterized by X-ray crystallography.
