Article Abstract
Through the use of (Bu4N)2[Sn3S4(edt)3] (edt=SCH2CH2S(2-)) and Sn(SPh)4 as metalloligands, three neutral compounds have been obtained: [(Ph3P) 2Cu] 2SnS(edt)(2).2CH2Cl2.H2O (1a), [(Ph3P) 2Cu]2SnS(edt)2.2DMF.H2O (1b), and [(Ph3P)Cu] 2Sn(SPh)(6).3H 2O (2). Single-crystal X-ray diffraction studies revealed that compounds 1a and 1b contain the same neutral butterfly-like [(Ph3P)2Cu]2SnS(edt)2 cluster, which consists of one central SnS 5 dreich trigonal bipyramid sharing one vertex and two sides with two slightly distorted CuS 2P2 tetrahedrons. Compound 2 has a linear [(Ph3P)Cu]2Sn(SPh)6 cluster that is composed of a central distorted SnS 6 octahedron sharing two opposite planes with two slightly distorted CuS 3P tetrahedrons. Compound 1a exhibited an emission at 568 nm (tau=12.86 micros) in the solid state, while in CH 2Cl 2 solution, 1a exhibited a green emission at 534 nm (tau=4.75 micros). Compound 2 showed an intense red emission at 696 nm (tau=3.64 micros) upon excitation at 307 nm in the solid state.

Enhancing the mechanistic regulation of the oxygen evolution reaction (OER) is crucial for developing efficient and stable electrocatalysts. However, the dynamic variation of surface structure during the electrocatalytic process limits the accurate identification of the active source and underlying reaction mechanism. Herein, we report an iodine-doping strategy to direct the reconstruction of active species in CuS catalysts toward an unconventional oxygen vacancy oxidation mechanism, thereby overcoming the activity and stability limitations.

The quad-tree plus multi-type tree (QTMT)-based coding unit (CU) partition accounts for most of the encoding time in VVC encoding. This paper proposes a data-driven fast CU partition approach based on an efficient Transformer model to accelerate VVC inter-coding.

Seeking new and efficient thermoelectric materials requires a detailed comprehension of chemical bonding and structure in solids at microscopic levels, which dictates their intriguing physical and chemical properties. Herein, we investigate the influence of local structural distortion on the thermoelectric properties of TlCuS, a layered metal sulfide featuring edge-shared Cu-S tetrahedra within CuS layers. While powder X-ray diffraction suggests average crystallographic symmetry with no distortion in CuS tetrahedra, the synchrotron X-ray pair distribution function experiment exposes concealed local symmetry breaking, with dynamic off-centering distortions of the CuS tetrahedra.

The semiconducting behavior of mixed-valence copper sulfides arises from the pronounced covalency of Cu-S bonds and the exchange coupling between Cu and Cu centers. Although electrocatalytic study with digenite CuS and covellite CuS has been performed earlier, detailed redox chemistry and its interpretation through lattice structure analysis have never been realized. Herein, nanostructured CuS and CuS are prepared and used as electrode materials to study their electrochemistry.

The reaction of 2-benzimidazolethiole (2-BIT) with copper dichloride in the presence of two equivalents of triphenylphosphine led to a binuclear complex of the type [Cu(µ-S-2-BIT)2(Ph3P)2Cl2]: dichloridobis(μ-1,3-dihydro-2H-benzimidazole-2-thione)bis(triphenylphosphi ne)-di-copper. The Cu(I) compound has been fully identified by elemental analysis, molar conductivity, FT-IR, UV/Vis, and single-crystal X-ray diffraction (XRD). The XRD study reveals that the complex has distorted tetrahedral geometry around the Cu(I)center, which contains two bridge sulfur atoms.
