Structural investigation on toluene-3,4-dithiolatoantimony(iii) alkyldithiocarbonate complexes: thermal, powder XRD and biological studies

Abstract

On thermal decomposition of the mixed sulfur donor antimony(iii) complexes, we obtained antimony sulfide at 600 °C, which was confirmed by scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX).

Preparation, spectroscopic, thermal and powder X‐ray diffraction characterization, and antimicrobial activities of mixed bis(O,O′‐diisopropyldithiophosphato‐S,S′)antimony(III) derivatives with some oxygen and sulfur donor ligands

“…00–042‐1759 and 00–070‐1332. It has been observed that the complexes have a crystalline structure, nanometric particles sizes of 14.67 and 11.39 nm characteristic of nanoparticles, lower symmetry (monoclinic) with unit cell volume of 4968.47 and 5079.79 Å 3 and have been calculated using the following formulae: …”

“…The presence of a lone pair of electrons on the metal present in the complexes which does not take part in the bonding results in a distorted octahedral geometry, due to which the complexes have lower symmetry (monoclinic). The mean crystallite size can be determined from the full width at half maximum of the diffraction peaks using the Debye–Scherrer formula: where D is the particle size, K a constant whose value is approximately 0.9, λ the wavelength of the X‐rays, B the full width at half maximum and θ the Bragg angle.…”

Syntheses, characterization, powder X‐ray diffraction analysis and antibacterial and antioxidant activities of triphenylantimony(V) heteroleptic derivatives containing substituted oximes and morpholine dithiocarbamate

“…Dithiocarbamates are a class of metal‐chelating, antioxidant compounds with various applications in chemistry, industry, agriculture and medicine for treatment of bacterial and fungal infection and possible treatment in AIDS; pyrrolidine iron dithiocarbamate derivatives were considered for treatment of AIDS as they can potently block a transcription factor involved in HIV . Antimony sulfur complexes have many potential applications in various fields such as thermoelectric cooling technologies, solar energy conversion, optoelectronic devices and microwave devices due to their semiconducting property . Dithiocarbamates stabilize high oxidation states in metal complexes, reflecting strong o‐bonding characteristic of dithiocarbamates in which there is an additional n‐electron flow from nitrogen to sulphur via planar delocalized π‐orbital system, as shown below: …”

Electrodeposition of Antimony from Hydrated Ammonium Aluminum Sulfate-Urea Room Temperature Ionic Liquid

“…(2)(b),(d) and (f), which might be related to the particle shapes, which disperse light allowing very small light reflection. The EDAX spectrum of antimony nanoparticles deposited on copper substrate appeared as M α and L α at (0.4 and 3.6) Kev as compared with standard values from energy table for EDAX analysis and as reported by H.Chauhan and coworkers [14], shown in Figure (3).The EDAX analysis confirmed the presence of small amounts of antimony with 3.47 At.%, 3.95At.% and 4.47At.% at one, two and three hours samples respectively. AFM images of the electrodeposited antimony are shown in Fig.(4).…”
