Use of Dialkyldithiocarbamato Complexes of Bismuth(III) for the Preparation of Nano- and Microsized Bi₂S₃ Particles and the X-ray Crystal Structures of [Bi{S₂CN(CH₃)(C₆H₁₃)}₃] and [Bi{S₂CN(CH₃)(C₆H₁₃)}₃(C₁₂H₈N₂)]

Abstract

A range of bismuth(III) dithiocarbamato complexes were prepared and characterized. The X-ray crystal structures of the compounds [Bi{S 2 CN(CH 3 )(C 6 H 13 )} 3 ] (1) and [Bi{S 2 CN(CH 3 )-(C 6 H 13 )} 3 (C 12 H 8 N 2 )] (2) are reported. The preparation of Bi 2 S 3 particulates using a wet chemical method and involving the thermalysis of Bi(III) dialkyldithiocarbamato complexes is described. The influence of several experimental parameters on the optical and morphological properties of the Bi 2 S 3 powders was investigated. Nanosized Bi 2 S 3 colloids were obtained having long-term stability and showing a blue shift on the optical band edge; the presence of particles exhibiting quantum size effects is discussed. Morphological welldefined Bi 2 S 3 particles were obtained in which the fiber-type morphology is prevalent.

Controllable synthesis of Bi2S3 hierarchical nanostructures: Effect of addition method on structures

“…Moreover, analogous to the complex (Bi(S 2 CNMe n Hex) 3 [50], the molecular (Bi(S 2 COC 3 H 7 ) 3 comprises a bismuth atom coordinated by three bidentate O-isopropyldithiocarbonate ligands. As the solution phase thermolysis of Bi(S 2 COC 3 H 7 ) 3 processed, the ligands may control the growth rate of different crystal faces through coordination interaction with bismuth (III), which results in the formation of one-dimensional Bi 2 S 3 nanostructures.…”

“…Many techniques including singlesource precursor method [25,26], hydrothermal or solvothermal decomposition [27][28][29][30][31][32], solventless thermolysis [33], microwave irradiation [34], sonochemical method [35] and self-sacrificing template route [36] have been applied to prepare one-dimensional Bi 2 S 3 nanostructures such as nanorods, nanowires and nanobelts. More complex patterns of Bi 2 S 3 such as flowers [14], urchins [37], snowflakes [38], sheafs [13], globules [39], microhedgehogs [40], dandelions [41], cauliflowers [42] have been made by employing biomolecule-assisted method [14,38], microwave-irradiated technique [37], colloidal solution method [13], interface growth technique [39], electrochemical synthesis [40] and wet chemical routes [41,42], respectively.…”

Great influence of a small amount of capping agents on the morphology of SnS particles using xanthate as precursor

“…Recently, the syntheses of semiconductor nanocrystals through a single-source precursor route have attracted much attention because of its potential advantages and possibility to tune the size and size distribution of the products by controlling the reaction conditions [18][19][20][21][22][23][24]. Those precursors were usually metal complexes and prepared based on the reaction of metal salt and ligands.…”

Novel one-pot synthesis and sensitisation of new BiOCl–Bi2S3 nanostructures from DES medium displaying high photocatalytic activity

“…This approach shows advantages over other methodologies reported in the past in which high reaction temperature, capping agents and use of less environmentally friendly reactants were required. [29][30][31][32] The presence of Bi2S3, which has a band gap energy in the range 1.2 to 1.8 eV 26,[33][34][35] , extends the absorption of the hybrid material to the visible region since BiOCl only absorbs in the UV (Eg BiOCl bulk = 3.5 eV). The BiOCl/Bi2S3 nanomaterials exhibit efficient visible light photocatalytic activity towards RhB, 2,4-dichlorophenol and MO degradation processes.…”
