A series of iron tricarbonyl α-diimine complexes, Fe(ArDABMe)(CO)3, were synthesized, in which the identity aryl substituent on ligand was varied (ArDABMe = Ar-NC(Me)-(Me)CNAr; 2a Ar C6H5; 2b 3,5-(CH3)2C6H3; 2c 2,4,6-(CH3)3C6H2; 2d 3,5-Cl2C6H3), and complexes characterized by 1H 13C NMR spectroscopy. The IR spectra compounds 2a-d exhibit three carbonyl stretches between 2040 1950 cm−1, all four...

In this paper we present new copper(i) iodide or copper(i) thiocyanate complexes with hydroxymethyldiphenylphosphine (PPh2(CH2OH)) or phosphine derivatives of sparfloxacin, a 3(rd) generation fluoroquinolone antibiotic agent (PPh2(CH2-Sf)) and 2,9-dimethyl-1,10-phenanthroline (dmp) or 2,2'-biquinoline (bq) auxiliary ligands. The synthesised complexes were fully characterised by NMR and UV-Vis s...

The coordination versatility of a 1,3,5-triphenylbenzene-tris-mesoionic carbene ligand is illustrated by the preparation of complexes with three different metals: rhodium, iridium and nickel. The rhodium and iridium complexes contained the [MCl(COD)] fragments, while the nickel compound contained [NiCpCl]. The preparation of the tris-MIC (MIC = mesoionic carbene) complex with three [IrCl(CO)2] ...

Dinuclear nickelphenoxyiminato olefin polymerization catalysts based on rigid p-terphenyl frameworks are reported. Permethylation of the central arene of the terphenyl unit and oxygen substitution of the peripheral rings ortho to the aryl-aryl linkages blocks rotation around these linkages allowing atropisomers of the ligand to be isolated. The corresponding syn and anti dinickel complexes (25-...

Two new nano particles of copper (II) and nickel (II) complexes, [Cu(cd5Clsalen)] (1) and [Ni(cd5Clsalen)] (2) with unsymmetrical tetradentate Schiff base ligand cd5Clsalen={methyl-2-[N-[2-(2-hydroxy-5-choloro-2phenyl) methylidynetrilo]ethyl}amino-1-cyclopentenedithiocarboxylate, were synthesized by hydrothermal method. These compounds were characterized by a variety of physic-chemical techniqu...

Density functional theory (DFT) calculations were comparatively carried out to reveal the origins of different catalytic performances from phosphine–benzene sulfonate (A, [{P^O}PdMe(L)] (P^O = Κ2-P,O-Ar2PC6H4SO3 with Ar 2-MeOC6H4)) and α-diimine (B, [{N^N}PdMe(Cl)] (N^N (ArN=C(Me)-C(Me)=NAr) 2,6-iPr2C6H3)) palladium complexes toward copolymerization ethylene methyl vinyl sulfone (MVS). Having a...

The syntheses and X-ray crystal structures of dinuclear μ-azido and μ-nitrido bridged iridium complexes bearing the pyridine, diimine ligand (PDI) are reported. Their electronic structures and formal oxidation states of the metal centers are analyzed by theoretical and experimental methods, revealing the non-innocence of the PDI and nitrido ligands.

The electronic structures of two uranium compounds supported by redox-active α-diimine ligands, ((Mes)DAB(Me))(2)U(THF) (1) and Cp(2)U((Mes)DAB(Me)) (2) ((Mes)DAB(Me) = [ArN═C(Me)C(Me)═NAr]; Ar = 2,4,6-trimethylphenyl (Mes)), have been investigated using both density functional theory and multiconfigurational self-consistent field methods. Results from these studies have established that both u...

Several photoactive platinum alpha-diimine intercalators have been prepared to develop new probes of DNA oxidation and reduction chemistry. Five water-soluble bis(mes')Pt(II) complexes (mes' = N,N,N,3,5-pentamethylaniline) with various aromatic alpha-diimine ligands (dppz = dipyridophenazine, np = naphtha[2,3-f][1,omega]phenanthroline, CN-np = naphtho[2,3-f][1,10]phenanthroline-9-carbonitrile, ...
