“…In the equatorial conformation of the ligand, C−Se−Se bond angles of 104.5 and 102° are in the range reported for other organic diselenides (92° for (3‐CF 3 ‐pySe) 2 , 102.7° for (5‐CF 3 ‐pySe) 2 , 104.7° for (pySe) 2 , etc.) . The C−Se and Se−Se bond lengths are also in the range of what found in most of the organic diselenides, i. e. (1.91–1.97 Å) and (2.285–2.33 Å), respectively …”

Synthesis, Characterization and Photo Response Behaviour of InSe and CuInSe₂ Nanostructures Using Tris(5‐methyl‐2‐pyridylselenolato)indium(III) as Molecular Precursor

This report presents the synthesis of organoselenium compound {SeC5H3(Me‐5)N}2 (1) and corresponding derivative of In(III), [In{SeC5H3(Me‐5)N}3] (2) and their characterization by elemental analysis, heteronuclear NMR (1H, 13C, 77Se) spectroscopy and single crystal X‐ray diffraction. The utilization of In(III) complex as molecular precursor has been demonstrated for the preparation of rare cubic phase of InSe. The complex has also been used for the preparation of tetragonal CuInSe2. The crystal structure, phase purity, morphology and elemental composition of these nanostructures were evaluated by powder X‐ray diffraction and electron microscopic techniques. The effect of increase in temperature is manifested in the increase of particle size of InSe and morphological variation from sheet to polygon in case of CuInSe2. The optical band gap of the nanostructures as deduced from diffuse reflectance spectroscopy (DRS) found to be in the range 1.84‐1.75 eV for InSe and 1.99‐1.78 eV for CuInSe2 which are optimum for solar energy harvesting. The band gap values are blue shifted relative to their respective bulk counterparts indicating quantum confinement effect in the nanostructures. Both InSe and CuInSe2 nanostructures showed photo response with faster switching characteristics which makes them promising candidate for alternative low cost photon absorber material.

Homoleptic copper and silver compounds of a series of pyrimidine-2-thionato derivatives (RpymS -; R = 4,6-Me 2 ,5-Et; 4-CF 3 ; 4,6-CF 3 ,Ph) have been synthesized by electrochemical oxidation of anodic metal (copper or silver) in a cell containing an acetonitrile solution of the appropriate thione and a small amount of tetraethylammonium perchlorate as electrolytic carrier. Subsequent reaction of these pyrimidine-2-thionato compounds with triphenylphosphane or bis(diphenylphosphanyl)methane (dppm) in acetonitrile allowed the synthesis of the corresponding heteroleptic complexes.

“…Pertaining to the novelty of the structural motifs of the compounds presented in this report, it should be mentioned that symmetrical binuclear Cu I compounds similar to 1 and 2 , with the general formula [(P^P)(κ‐S‐thiolate)Cu(µ‐P^P)Cu(κ‐S‐thiolate)(P^P)] with two chelating and one bridging dppe (P^P) and two terminal thiolate ligands (Scheme A), have been reported in the past . The unsymmetrically substituted, binuclear compound [(dppe)(κ‐S‐mtdzt)Cu(µ‐dppe)CuI(dppe)] ( 3 ), having different anionic ligands coordinated to the two Cu centers, is reported for the first time.…”

Binuclear Copper(I) Compounds with N‐Heterocyclic Thiolate and Diphosphane Ligands: Effects of Thiolate Ligands on Solid‐State Molecular Structures and Luminescence Properties

et al. 2018

View full text Add to dashboard Cite

A series of four photoluminescent binuclear copper(I) compounds bearing phosphorus and sulfur donor atom ligands have been synthesized from reactions of copper(I) halides with the diphosphane dppe [1,2-bis(diphenylphoshino)ethane] and the anions of three different N-heterocyclic thiols, namely 5-methyl-1,3,4-thiadiazole-2-thiol, 1-phenyl-1H-tetrazole-5-thiol and ethyl 2-thiouracil-5-carboxylate. Depending on the nature of the N-heterocyclic thiol, the resulting compounds adopt two different structural motifs, having either a dppebridged core, that is, [Cu 2 (κ-S-thiolate) 2 (dppe) 2 (μ-dppe)], or a bis(thiolate)-bridged core, that is, [Cu 2 (μ-S-thiolate) 2 (dppe) 2 ], with a Cu 2 (μ-S) 2 cluster-type core. The stabilization of the latter type of structure is rationalized by the presence of intramolecular hydrogen-bonding interactions developed between two bridging N-heterocyclic thiolate ligands positioned at the same side of the Cu 2 (μ-S) 2 core, which lead to short Cu···Cu interactions (ca. 2.6 Å), as it is evidenced by X-ray crystallography stud- [a]
