have chlorine bridged distorted-octahedral geometry. It has been observed that the dithiocarbamato moiety is symmetrically bonded in all the cases. A three stage TGA profile is observed for all the complexes leading to the formation of respective metal sulfide as the end-product. The molar conductance of 10 -3 mol L -1 solution of the complexes measured in DMSO is indicative of their non-ionic nature. Keywords: dithiocarbamates, transition metals, thermal analysis, symmetrical bonding IntroductionDithiocarbamates are used to stabilize a wide range of oxidation states of different metal ions. 1 A large number of compounds are known where CS 2 binds in η 1 -end on, η 2 -side or in η 3 -coordination modes. 2-4 The major advantage of using the small bite-angle of dithiocarbamato moiety as a stabilizing chelating ligand, is its unique property to remain intact under a variety of reaction conditions. 5 Nowadays copper(II) dithiocarbamate is successfully used as single source precursor for the growth of semiconducting copper sulfide thin films. 6 The iron(II), iron(III) dithiocarbamates have been studied for their spincrossover phenomenon, 7 radical traps for NO, 8 and as antioxidants and pro-oxidants in biological systems. 9 Diethyl dithiocarbamates are also known to inhibit the activity of Cu/Zn-superoxidedismutase (SOD) through the withdrawal of copper from the protein both in vivo and in vitro. 10 Some dialkyl-substituted dithiocarbamates have proved to be an efficient anti-alkylating, anti-HIV and froth-floatation agents. 11 The optical and electrochemical properties of dithiocarbamates can effectively be used to construct sensors for guest molecules and macromolecules. [12][13][14] In this paper, we report a convenient one-pot synthesis of the transition metal dithiocarbamates via template procedure. In the present work, a condensation reaction was carried out between acetylacetone, ethylenediamine, 108 Siddiqi et al. J. Braz. Chem. Soc. carbon disulfide in a single step leading to the formation of a ring like complex ( Figure 1 and Figure 2). ExperimentalHydrated metal chlorides (BDH) acetylacetone, carbon disulfide (Merck) and ethylenediamine (Ranbaxy) were used as received. Methanol was used after distillation. Elemental analyses (C, H, N and S) were carried out with a Flash EA-1112 Analyser, CE Instrument. IR spectra (4000-400 cm -1 ) were recorded on a FT-IR Perkin-Elmer Spectrum BX as KBr disc while the 600-200 cm -1 range were scanned on CsI on Nexus FT-IR Thermo Nicolet, Madison Wisconsin. The conductivity measurements were carried out with a CM-82T Elico conductivity bridge in DMSO. The electronic spectra were recorded on a Cintra 5GBC spectrophotometer in DMSO. Magnetic susceptibility measurements were done with a Sherwood Scientific MSB Auto at room temperature. TGA/DSC was performed with a Universal V3.8 B TA SDT Q600 Build 51 Thermal Analyzer under nitrogen atmosphere using alumina powder as reference material. The heating rate was maintained at 10 °C min -1 . The metal contents were estimated by...

“…It is a IV-VI layered compound semiconductor with distorted NaCl type orthorhombic crystal structure [3]. Due to its interesting structural, optical and electrical properties, SnS has become an important material for optoelectronics and photovoltaics [4][5][6][7] with many promising technological applications [8,9]. Further, properties like high absorption coefficient [10], direct band gap in the range 1.2-1.5 eV and indirect band gap in the range 1.0-1.2 eV [7,11] make SnS a more viable material for photovoltaic applications.…”

SnS thin films were prepared using automated chemical spray pyrolysis (CSP) technique. Single-phase, p-type, stoichiometric, SnS films with direct band gap of 1.33 eV and having very high absorption coefficient (N 10 5 /cm) were deposited at substrate temperature of 375°C. The role of substrate temperature in determining the optoelectronic and structural properties of SnS films was established and concentration ratios of anionic and cationic precursor solutions were optimized. n-type SnS samples were also prepared using CSP technique at the same substrate temperature of 375°C, which facilitates sequential deposition of SnS homojunction. A comprehensive analysis of both types of films was done using x-ray diffraction, energy dispersive x-ray analysis, scanning electron microscopy, atomic force microscopy, optical absorption and electrical measurements. Deposition temperatures required for growth of other binary sulfide phases of tin such as SnS 2 , Sn 2 S 3 were also determined.

“…2 -7 The simple alkyl halides, such as MeSnCl 3 , are tetrahedral in the gas phase, 8 and in the crystal MeSnCl 3 9 and MeSnBr 3 10 are essentially isostructural, with near-tetrahedral molecules very weakly bridged through two of the three halogen atoms, as shown in Scheme 1(a). In MeSnI 3 the discrete tetrahedral molecules show no significant interaction.…”

Three monoorganotin(IV) compounds of general formula LCNSnX3, where LCN is a 2‐(dimethylaminomethyl)phenyl‐ group and X = Cl (1), Br (2) and I (3), were prepared and characterized using XRD and NMR techniques. Compound 1 reacts with moisture producing [(LCN)2HSnCl2]+ [LCNSnCl4]−. Compound 3 decomposes to (LCN)2SnI2, SnI2 and I2 when heated. Compound 2 was reacted with NH4F yielding an equilibrium of fluorine‐containing species. The major products were [LCNSnF5]2− and [(LCNSnF3)2(µ2‐F)2]2− (4a). When compound 2 was reacted with another fluorinating agent, LCN(n‐Bu)2SnF, an oligomeric product, [LCNSnF2(µ2‐F)2]n, was observed. Further addition of NH4F led to subsequent formation of 4a. The structure of fluorinated products was investigated by 1H, 19F and 119Sn NMR spectroscopy. Copyright © 2006 John Wiley & Sons, Ltd.
