Silver(I) and gold(I) complexes of multidentate ligands based on functionalized pyridine

Silver(i) complexes containing heteroleptic diorganochalcogen(ii) ligands

“…With this in mind, we have extended our studies in the field of the coordination chemistry of organochalcogen( ii ) compounds containing organic groups with donor atoms capable of intramolecular interactions ( i.e. [R 2 C(OH)CH 2 ](2-Me 2 NCH 2 C 6 H 4 )E (E = S, Se, Te; R = Me, Ph), 17 [2-(R 2 NCH 2 )C 6 H 4 ][(3,5-dmpz)CH 2 CH 2 ]Se (R = Me, Et, dmpz = dimethylpyrazole), 18 ( n -Bu)(2-Me 2 NCH 2 C 6 H 4 )Se, 19 2,6-[{2′-(R 2 NCH 2 )C 6 H 4 }SeCH 2 ] 2 C 5 H 3 N (R = Me, Et) 20 ) to the synthesis, structural characterization and reactivity towards silver( i ) species of the new heteroleptic diorganochalcogen( ii ) ligands containing 2-C 6 H 5 -(4 H )-oxazol-5-one incorporated into the skeleton of the ligand to achieve optical properties.…”

“…Although the ability of 2-C 6 H 5 -(4H)-oxazol-5-ones to promote optical properties is well known and Pd(II) complexes have been investigated for their photophysical properties, 16 silver(I) complexes containing multidentate organochalcogen(II) ligands incorporating such fragments into their skeleton have not yet been studied. With this in mind, we have extended our studies in the field of the coordination chemistry of organochalcogen(II) compounds containing organic groups with donor atoms capable of intramolecular interactions 20 ) to the synthesis, structural characterization and reactivity towards silver(I) species of the new heteroleptic diorganochalcogen(II) ligands containing 2-C 6 H 5 -(4H)-oxazol-5-one incorporated into the skeleton of the ligand to achieve optical properties. 5); S (6)] were isolated as intense yellow solids, in very good yields.…”

Metal Complexes Containing Homoleptic Diorganoselenium(II) Ligands: Synthesis, Characterization and Investigation of Optical Properties

“…For years, our research interests have been focused on the synthesis and structural characterization of metal complexes with organochalcogen multidentate ligands for potential applications in optoelectronics and material science, e.g., complexes of heteroleptic organochalcogen ligands containing nitrogen and chalcogen donor atoms with coinage metals [ 12 , 13 , 14 ], group 12 [ 15 , 16 ] and tetrels [ 17 ]. In the attempt to obtain metal complexes with photophysical properties and potential applications in optoelectronics, in the present study, we designed new homoleptic diarylselenides with organic substituents containing oxazolone fragments in their skeletons as ligands to build metal complexes.…”
