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. We gratefully acknowledge the financial assistance of Technical
Research Council of Turkey (grant nos. TBAG 114Z091).
