“…14 Other strategies to produce Bi 2 S 3 nanostructures have been described. 6, [15][16][17][18][19][20][21][22][23][24][25][26][27][28] It is almost certain that the conversion to nanoparticles in these systems involves prior coordination of the S-based ligand, and decomposition of preassembled sulfur-containing bismuth(III) complexes may afford some advantages in control over the shape and size of the particles formed. [15][16][17][18][19][20][21] Bismuth(III) routinely adopts coordination numbers higher than six and stable aminopolycarboxylate (APC) and polyaminopolycarboxylate (PAPC) complexes that also contain sulfur-based ligands have been reported.…”

Synthesis of Bi₂S₃ Nanostructures from Bismuth(III) Thiourea and Thiosemicarbazide Complexes

Rod-shaped nanostructures of Bi2S3 were synthesized by the solution decomposition of the two new bismuth(III) complexes [Bi6(pydc)8(Hpydc)2(tu)8] (1) and {[Bi2(pydc)3(tsc)(H2O)2]·H2O}∞ (2) (H2pydc = 2,6-pyridinedicarboxylic acid also known as dipicolinic acid; tu = thiourea, tsc = thiosemicarbazide). They were obtained by treatment of Bi2O3 with dipicolinic acid in the presence of the sulfur-containing ligands. The complexes were characterized with the aid of elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. The dipicolinate anions behave as tridentate ligands toward Bi(III), but two modes of coordination are found. In both cases the ligand serves as a pincer ligand O,N,O-bonded to one bismuth(III) center, but it can also function as a bridging ligand through one carboxylate group that assembles into hexanuclear molecules (1) or a polymeric chain (2). The air-stable complexes 1 and 2 have been used as starting materials in the preparation of bismuth sulfide nanoparticles (NPs) in the presence of different surfactants. Decomposition of 1 and 2 gave Bi2S3 in all cases, but addition of a small amount of 1-dodecanethiol (DT) or 1-octadecanethiol (OT) at 120 °C resulted in better crystallite growth with the observation of nanorods up to several hundreds of nanometers in length. These were examined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The influence of various reaction conditions on the shape and size of the nanocrystals is discussed. The high resolution (HR) TEM images reveal a number of linear and planar crystal defects and atomic distortions that account for the splitting of bismuth sulfide nanocrystals as observed previously. The growth mechanism is believed to involve decomposition of the precursors and formation of Bi2S3 seeds, followed by the preferential [001] growth of larger particles. Crystal splitting caused by defects and atomic distortions as well as Ostwald ripening processes play important roles in shaping the morphologies of the final Bi2S3 nanostructures.

“…The weak peak around 1356 cm -1 appearing in all the samples may be assigned to C-S and C-N stretching vibration [30]. A strong intensity band present in the region 567 cm -1 may be attributed to the symmetric and asymmetric vibrations of sulphur, while a medium intensity band in the region 460-403 cm -1 can be assigned to bismuth [31].…”

One dimensional Bi2S3 nanorods have been successfully synthesized by a very simple reflux method with different precursor concentration for 2 hours at 180 �C. The as-synthesized Bi2S3 powders were characterized by X-ray diffraction (XRD), high resolution scanning electron microscope (HRSEM), high resolution transmission microscope (HRTEM), UV-Vis spectrometer, Fourier transform infrared (FTIR) spectrometer. X-ray diffraction (XRD) results show that the resulting nanocrystals have an orthorhombic structure. X-ray diffraction patterns indicate a polycrystalline nature and the crystallite sizes seem increase with increase in the concentration. The HRSEM and HRTEM images reveal that the diameter of the nanorods increase with increasing concentration of the precursor. Morphological analysis reveals that the as-prepared Bi2S3 nanorods can be tuned to morphology by varying precursor concentration from 0.01 M to 0.001 M. The bismuth nitrate, which is known to be a linear polymer, plays a critical role as a precursor and a template for the growth of uniform Bi2S3 nanorods. Bi2S3 nanorods are good absorbents of solar radiation and hence can be used in solar cells.

“…7 Cyclic O,O -alkylenedithiophosphates of transition metals have been extensively studied, [8][9][10] and the studies have also been extended to the derivatives of nontransition metals, including organoantimony(III) moieties. [11][12][13][14][15][16][17] Metal derivatives of antimony(III) containing alkylenedithiophosphates also exhibit significant antimicrobial activities. 16,17 Although chloro bis(dialkyldithiophosphates) antimony(III) [(RO) 2 P(S)S] 2 SbCl 18,19 [where R = Et, Pr i , Pr n and Bu n ] and only one compound of chloro bis(alkylenedithiophosphates) antimony(III) [OGOP(S)S] 2 SbCl 12 [where G = CH(CH 3 ) CH(CH 3 ) ] have been reported, heterobinuclear compounds of antimony containing alkylenedithiophosphates have not been reported to date.…”

Chloro bis(alkylenedithiophosphato)antimony(III) complexes of the type [OGOP(S)S] 2 SbCl(1-5) [where G = C(Me) 2 CH 2 CH(Me) {1} C(Me) 2 C(Me) 2 {2}, CH 2 C(Me) 2 CH 2 {3}, CH(Me) CH(Me) {4} and -CH(Me) CH 2 CH 2 {5}] have been synthesized by the reaction of SbCl 3 with sodium salts of alkylenedithiophosphoric acids in a 1:2 molar ratio in refluxing benzene. Reactions of chloro bis(alkylenedithiophosphato) antimony(III) compounds, [OGOP(S)S] 2 SbCl with sodium tetraisopropoxoborate, NaB(OPr i ) 4 , in a 1:1 molar ratio in refluxing benzene yielded some new heterobinuclear derivatives of antimony(III) and boron(III) of the type[OGOP(S)S] 2 Sb(µ OPr i ) 2 B(OPr i ) 2 . These newly synthesized complexes have been characterized by elemental analysis and molecular weight measurement, and their plausible structures have been proposed on the basis of IR, NMR ( 1 H, 13 C, 31 P, 11 B), and FAB-mass spectral studies. On the basis of the spectroscopic evidence, a pseudo octahedral geometry around antimony and tetrahedral geometry around boron atom has been proposed. Cyclic O,O -alkylenedithiophosphate ligands and their corresponding chloro bis(alkylenedithiophosphato)antimony(III) compounds have been screened for microbial activities. These compounds showed significant antifungal activity against Fusarium and Trichoderma and antibacterial activity against E. Coli and Pseudomonas.
