“…In both complexes, the Cd-S and Cd-I bond lengths (Table 3) are in agreement with those reported for related compounds [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The SCN 2 moieties are essentially planar with bond lengths corresponding to values intermediate between single and double bonds.…”

“…In view of this, cadmium(II) complexes of thiones have been widely studied in recent years [8][9][10][11][12][13][14][15][16]. The structural studies on cadmium(II) halide complexes of thiones describe that in most of the cases the structures consist of discrete mononmeric molecules with cadmium adopting a somewhat distorted tetrahedral coordination geometry [11][12][13][14][15][16][17][18][19][20][21][22][23]. In some cases, polymeric structures are obtained through sulfur and halide bridging consisting of [CdS 3 X 3 ] distorted octahedra [18,19].…”

Two cadmium(II) iodide complexes, [Cd(Detu) 2 I 2 ] (1) and [Cd(Diaz) 2 I 2 ] (2) (Detu = N,N 0 -diethylthiourea; Diaz = 1,3-diazinane-2-thione) have been prepared and their structures been determined by X-ray crystallography. The crystal structures show that both complexes are mononuclear with the cadmium atom coordinated to two iodide ions and two thione ligands adopting a distorted tetrahedral geometry. Whereas, 2 exists as discrete monomeric species, the structure of 1 consists of three crystallographically independent molecules. The complexes were also characterized by IR and NMR ( 1 H and 13 C) spectroscopy.

“…The carbon atoms in the -CH 2 groups on PETU responsible for the shift could be observed at about 40-56 ppm and carbon atoms in -C=S have been detected about 184 ppm (Fig. 3) [27,33,[40][41][42][43][44][45][46][47][48]. The thermal stability of the thiourea polymers was investigated by TGA measurements.…”

In this study, in order to obtain polymeric thiourea compounds which have unsolubulity properties and higher metal content, new reaction pathways based on the use of the template effect were investigated. For this purpose, the reactions between different diamines, such as ethylendiamine, ortho (o-) and para (p-) phenylenediamine, and carbon disulfide (CS 2 ) were investigated and optimized by using the template effect of Ni(II). Catalytic activity of the polymeric structure on oxidation of styrene was also investigated in terms of different parameters such as heat (25 and 80 • C), time (4 and 8 h), oxidant hydrogen peroxide (H 2 O 2 ), tert-butyl hydroperoxide (TBHP), di-tert-butyl peroxide (DtBP) and solvent (acetonitrile and benzene). The products have been characterized on the basis of analytical and spectral method, Fourier transform infrared spectroscopy, 1 H-and 13 C-nuclear magnetic resonance, gel-permeation chromatography, elemental analysis, thermogravimetric analysis, atomic adsorbtion spectrometry, gas chromatography and gas chromatography mass spectrometry.

“…Cadmium Oxide (CdO) is a semiconductor of group II-VI with direct band gap of about 4.1 (eV) in room temperature and exciton binding energy of about 75 (meV) . Exciton recombination of Cadmium Oxide (CdO) nanoparticles leads to UV emission of about 415 nanometers [184][185][186][187][188][189][190]. Many researchers are interested in this characteristic of Cadmium Oxide (CdO) to be used in LEDs with short wavelength [191,192].…”

The effects of substrate temperature on the structural, optical, medical and electrical characteristics of Cadmium Oxide (CdO) films are investigated in the current study. Films are deposited on glass substrate at different temperatures, ranged between 450-600 ºC, using Spray Pyrolysis Technique. According to XRay Diffraction (XRD), it is found that the films are polycrystalline and Cadmium Oxide (CdO) is of a hexagonal wurtzite structure which the preferred direction of its crystal plane is (002). The maximum optical transmittance of films is more than 85%. The size of crystallites is calculated with the maximum value in 500º C. Furthermore, Cadmium Oxide (CdO) nanoparticles were synthesized in deionized water by laser ablation of Cadmium plate. In the current paper, the effects of laser pulse energy and wavelength on the characteristics of Cadmium Oxide (CdO) nanoparticles were studied. Analyses of Transmission Electron Microscope (TEM) were confirmed that size distribution of Cadmium Oxide (CdO) nanoparticles is reduced by increase in laser pulse energy. Fluorescence spectrum of Cadmium Oxide (CdO) nanoparticles shows violet emission accompanied by blue and green band. UV emission with high intensity shows that nanostructure of Cadmium Oxide (CdO) is of a little deficiency. Also, the current study aims to study the linear and non-linear optical characteristics of Cadmium Oxide (CdO) nanoparticles and their applications. Firstly, fluorescence spectrum, as a linear characteristics of Cadmium Oxide (CdO), as well as second harmonic generation and two photons absorption, as non-linear characteristics of Cadmium Oxide (CdO), are studied. Then, some aspects of medicinal and pharmaceutical applications of Cadmium Oxide (CdO) nanoparticles for eliminating cancer cells such as the effect of Cadmium Oxide (CdO) nanoparticles on DNA of human cancer cells and the interaction of Cadmium Oxide (CdO) nanoparticles with DNA of cancer cells are originally investigated. It should be noted that the range of considered parameters are separately clarified and explained in each of related sections (Figure 1).
