Khalaji4 1Department of Chemistry, Payame Noor University, Mashhad, Iran 2Department of Solid State Chemistry, Institute of Chemical Technology, Prague, Czech Republic 3Institute of Physics of the ASCR, Prague 8, Czech Republic 4Department of Chemistry, Faculty of Science, Golestan University, Gorgan, Iran E-mail: alidkhalaji@yahoo.com Received December, 12, 2013 In this paper, we report the preparation of a four-coordinated copper(I) thiosemicarbazone complex [CuI(PPh3)(catsc)] from the reaction of PPh3 and catsc (3-phenylpropenalthiosemicarbazone) with CuI. <...> The synthesized complex is characterized by elemental analyses (CHNS) and FT-IR spectroscopy. <...> The crystal structure of [CuI(PPh3)(catsc)] is investigated by single crystal X-ray diffraction. <...> The catsc coordinates to the copper(I) ion as a bidentate ligand via the N and S atoms. <...> The complex has a distorted tetrahedral coordination geometry. <...> Thiosemicarbazones, an important class of N,S-donor ligands, react with a range of transition metals [ 1, 2 ]. <...> In recent years, there was interest in thiosemicarbazones due to their structural diversity [ 3, 4 ] and anticancer, antibacterial, antifungal [ 5 ], and ion-sensing abilities [ 6 ]. <...> Comparing with other complexes, the coordination chemistry of copper(I) thiosemicarbazones is less investigated [ 7— 12 ]. <...> The main reason for limited information on copper(I) thiosemicarbazones is their insolubility in common organic solvents, such as methanol, chloroform, ethanol etc. <...> In the neutral form, thiosemicarbazone binds to a metal ion as a monodentate ligand via an S donor atom or as a bidentate ligand via S and N donor atoms. <...> Infrared spectra were recorded using KBr disks on a FT-IR Perkin—Elmer spectrophotometer. <...> The thiosemicarbazone ligand catsc was prepared in a high yield following the literature procedure [ 13 ]. <...> To a solution of 190 mg (1 mmol) CuI in 5 mll acetonitrile a solution of 262 mg (1 mmol) of PPh3 in 5 ml l acetonitrile was added dropwise under the air atomsphere at room temperature. <...> The mixture was stirred for 30 min and then 205 mg (1 <...>
