Luminescent rhenium(I) complex of azo ligand based on quinoline: Synthesis, characterization and computational investigations

Reaction of 7-(quinolin-8-yldiazenyl)quinolin-6-ol HL, [where H represents the dissociable proton upon complexation] based on quinoline with [Re(CO)5Cl] in toluene afforded brown colored product of composition [(Re(CO)3L]. The mononuclear Re(I) complex was characterized unequivocally. Molecular structure of the complex fac-[(Re(CO)3L] was confirmed by single-crystal X-ray diffraction. The complex exhibited excellent photoluminescence behavior in solution state. The ground and excited-state geometries and absorption properties of the Re(I), complex was further examined by DFT and TDDFT method

Electronic Tuning and Catalytic Activity of a Novel Pd(II) Complex Supported by a Tetracoordinate Ligand

The synthesis and study of a novel Pd(II) complex (2) supported by a new tetracoordinate ligand that is based on a bis(N-heterocyclic carbene) with two pendant pyrimidinyl donors is described. The complex was characterized using a series of spectroscopic, analytical, and computational techniques. A preliminary assessment showed that 2 displayed good performance in Suzuki-Miyaura coupling reactions between phenyl boronic acid and an assortment of substituted bromobenzenes. Finally, the intrinsic electronic characteristics of the complex were elucidated through DFT-based molecular orbital calculations which revealed that the coordinated metal center was relatively electron deficient and stabilized by a series of ligand dominated interactions

Synthesis, characterizations and structure of orthometallated Pt(II) and Pt(IV) complexes: Oxidative addition to C,N,N,O coordinated Pt(II) complexes

Reactions of 2-(arylazo)-1-N-salicylidene phenylamine, H2L, 1, [H represents the dissociable protons upon complexation], with K2PtCl4 afforded orthometallated complexes of composition [Pt(L)], 2 where the Pt(II) is coordinated by the tetradentate (C,N,N,O) ligand, L2-. Reaction of the precursor complex [Pt(L)] with I-2 afforded octahedral complexes of composition [PtI2(L)], 3. All the complexes were characterized unequivocally. X-ray crystal structure of [Pt(L-1)] and [Pt I-2(L-1)] have been determined. (C) 2014 Published by Elsevier Ltd
