3-benzoxazole (BBO) and triphenylphosphine sulfide (SPPh3) ligands, [Cu(BBO)(SPPh3)]ClO4}n (1), has been characterized by elemental analysis, UV-Vis, infrared spectra and single-crystal X-ray diffraction. The structural analysis revealed that 1 exhibits a one-dimensional CP and is in a three-coordinate slightly distorted trigonal planar environment in which the total angle around the copper(I) atom is 359.2°
Synthesis, structure, luminescence and electrochemical and antioxidant properties of anion‐controlled silver(I) complexes with 2,2′‐(1,4‐butanediyl)bis‐1,3‐benzoxazole
of various anions on the self‐assembly and properties of silver complexes, reactions of anions of silver salts with 2,2′‐(1,4‐butanediyl)bis‐1,3‐benzoxazole (BBO) afforded four complexes, formulated as [Ag2(BBO)2(p‐toluenesulfonate)2] (1), [Ag(BBO)(picrate)]}∞ (2), [Ag(BBO)1/2(o‐coumarate)]·DMF}∞ (3) and [Ag2(BBO)3](PF6)2}∞ (4). These complexes were characterized using elemental analysis, infrared
properties investigation show that complex 1 has two emission peaks, which attributed to the π*-π and π*-n transitions. However complex 2 only has one emission peak, which may be attributed to MLCT [d10(Cu)→π*]. This indicates that different types of N-heterocyclic ligands have an important influence on the structure and luminescent properties of copper(I) complexes.
Synthesis, structure, fluorescence, and electrochemical properties of a binuclear Ag(I) complex with 1,4-bis(benzo[<i>d</i>]oxazol-2-yl)butane as a ligand
described as distorted trigonal planar, with one oxygen atom from a perchlorate anion and two nitrogen atoms from two BBO ligands. The luminescence properties of the ligand and the Ag(I) complex were studied in the solid state. The emission peaks of the Ag(I) complex are attributed to ligand-centered transitions. There is no effect of the complexation except for a partial quenching. The cyclic voltammograms
