Single end-on azido bridged 1D chain copper(II) complex: Synthesis, X-ray crystal structure and catalytic activity in homogeneous epoxidation of cyclooctene

Structure, magnetic properties and DFT calculations of azido-copper(ii) complexes with different azido-bonding, nuclearity and dimensionality

Cu(ii) compounds derived from diamine substituted alkyl or phenyl groups with azido acting as the bridging ligand were synthesized and were structurally and magnetically characterized.

Preparation of a bispyridine based porous organic polymer as a new platform for Cu(ii) catalyst and its use in heterogeneous olefin epoxidation

A new type of bispyridine (bpy) incorporated POP was prepared via a cobalt-catalyzed acetylene trimerization. Subsequent metalation of CuCl₂ gave POP-Cu(ii) which displayed outstanding olefin oxidation activity.

Intrachain antiferromagnetic exchange in a 1D branched-chain built of two different copper(ii) centres interlinked by end-on azido and phenoxo bridges: electron density map, electrochemical and magnetic properties

A 1D, end-on azido- and phenoxo-bridged, coordination polymer, [Cu₂(μ-NAPPR)(μ_1,1-N₃)₂]_n (1), (NAPPR²⁻ = 1,3-bis(naphthylideneimino)propane dianion), was synthesized and characterized.

A new tridentate Schiff base Cu(II) complex: synthesis, experimental and theoretical studies on its crystal structure, FT-IR and UV-Visible spectra

A new Cu(II) complex [Cu(L)(NCS)] has been synthesized, using 1-(N-salicylideneimino)-2-(N,N-methyl)-aminoethane as tridentate ONN donor Schiff base ligand (HL). The dark green crystals of the compound are used for single-crystal X-ray analysis and measuring Fourier Transform Infrared (FT-IR) and UV-Visible spectra. Electronic structure calculations at the B3LYP and MP2 levels of theory are performed to optimize the molecular geometry and to calculate the UV-Visible and FT-IR spectra of the compound. Vibrational assignments and analysis of the fundamental modes of the compound are performed. Time-dependent density functional theory (TD-DFT) method is used to calculate the electronic transitions of the complex. A scaling factor of 1.015 is obtained for vibrational frequencies computed at the B3LYP level using basis sets 6-311G(d,p). It is found that solvent has a profound effect on the electronic absorption spectrum. The UV-Visible spectrum of the complex recorded in DMSO and DMF solution can be correctly predicted by a model in which DMSO and DMF molecules are coordinated to the central Cu atom via their oxygen atoms.
