“…The m(C=S) vibration, which occurs between 700 and 600 cm -1 for the free ligands, is shifted toward lower frequency upon complexation, in accordance with the data observed for the other thione complexes [34][35][36][37][38][39][40]. Another important vibrational band observed in IR spectra of the thiones is m(NH), which appears around 3,200 cm -1 .…”

“…In the 13 C NMR spectrum, the [C=S resonance of the ligands in the respective copper complexes is shifted upfield by about 4-13 ppm as compared to the free positions in accordance with the data observed for other complexes of d 10 metals with thiones [6,[34][35][36][37][38][39][40][45][46][47][48]. The upfield shift is attributed to the lowering of the [C=S bond order and a shift of N ?…”

“…The upfield shift is attributed to the lowering of the [C=S bond order and a shift of N ? C electron density, producing a partial double-bond character in the C-N bond [34][35][36][37][38][39][40]. As the shift difference in the [C=S resonance may be related to the strength the of metal-sulfur bond, Table 5 shows that the [Cu(Dphtu)Br] complex would be the most stable one among the complexes prepared within this work.…”

“…Some reports are also available on the antimicrobial activities of copper(I)-thione complexes [11,12]. We have been investigating the spectral and structural chemistry of coinage metal complexes of thiones in order to study their physical properties, the stereochemistry of the metal atoms, and the coordination modes adopted by the ligands [4,5,[19][20][21][22][34][35][36][37][38][39][40]. Here, we report on the synthesis, characterization, and antimicrobial properties of a number of copper(I) bromide complexes of thioureas.…”

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.032; wR factor = 0.088; data-to-parameter ratio = 20.9.The dinuclear title complex, [Ag 2 (C 6 H 7 N 2 S) 2 (C 18 H 15 P) 2 ], comprises two inversion-related [Ag(C 6 H 7 N 2 S)(C 18 H 15 P)] units. The pyrimidinethiolate anion acts both as a bridging and a chelating ligand. The Ag I ions are linked via two 2 -S donor atoms, which generate a strictly planar Ag 2 S 2 core with an AgÁ Á ÁAg separation of 2.9569 (4) Å . The Ag I ion presents a distorted tetrahedral coordination geometry. In the crystal, weak C-HÁ Á ÁN and C-HÁ Á ÁS hydrogen bonds link the complex molecules into a two-dimensional network parallel to (010). Related literature

The design, synthesis, and spectroscopic characterization of [Ag(P(o‐C6H4OCH3)3)(NO3)]2 (1) and [Ag(P(o‐C6H4OCH3)3)2][NO3] (2) were conducted to investigate the efficiency of the fabricated solar cell devices. The slow evaporation technique proved effective in growing the colorless crystals of the silver(I) complexes. Spectroscopic analyses including Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), and ultraviolet–visible (UV–Vis) studies were carried out to elucidate the chemical structure and absorption properties of the compounds. The chemical composition and existence of intermolecular interactions in 1 and 2 were disclosed via the single‐crystal x‐ray diffraction method. The side‐to‐side arrangement of molecules in 1 and 2 was evident from the crystal packing analysis, in which the molecules in both compounds were linked together by C–H···O and C–H···π contacts. The silver(I) complexes exhibited maximum absorption wavelength (287–288 nm) within the ultraviolet region, where both compounds had comparable high energy band gap values ranging from 4.15 to 4.16 eV. Moreover, both compounds possess appropriate HOMO–LUMO energy levels that facilitate effective electron injection and dye regeneration processes in dye‐sensitized solar cell (DSSC) applications. Photophysical characterization techniques, field‐emission scanning electron microscopy (FESEM), and energy‐dispersive x‐ray (EDX) spectroscopy studies were employed to assess the morphological characteristics and elemental composition of the silver(I) complexes on TiO2. Compound 2 exceeded 1 in terms of solar cell efficiency, 2 (η = 3.34%) > 1 (η = 0.66%) due to the complex being in ionic form and composed of the mononuclear [Ag(P(o‐C6H4OCH3)3)2]+ cation [NO3]− anion.
