a series of dissymmetric dinuclear complexes were synthesized, as dual site catalysts in ethylene polymerization,by coupling the allylated a-diimine complexes of the metals ti, zr, v, ni and pd with the ansa-zirconocenecomplex [c5h4-sih(me)-c5h4]zrcl2 possessing a hydride silane moiety. the different stages of syntheses includedthe formation of bis(cyclopentadienide)methyl silane which was util...

The Cu(II), Fe(II), Mn(II) and Zn(II) metal complexes of Schiff base 2-(salicylimino)-3-hydroxypyridine (SIHP) were prepared and characterized by various analytical techniques such as FTIR, UV-Visible spectroscopy and elemental analyses. The magnetic moment values suggested octahedral geometry for these transition metal complexes. Thermal stability of the compounds synthesized was also studied....

T metal complexes, and particularly ruthenium polypyridine complexes, can be used as catalysts or photocatalysts capable of performing water oxidation [1] or oxidation of organic compounds.[2,3] They can also be used as chromophores to harvest solar energy due to their absorption in the visible region. Therefore, understanding the nature of the electronic excited states in transition-metal comp...

Two univalent transition metal complexes, (micro-eta6:eta6-C7H8){MnAr*-3,5-Pri2}2 () and (eta6-C6H6)FeAr*-3,5-Pri2 () (Ar*-3,5-Pri2=C6H-2,6-(C6H(2)-2,4,6-Pri3)(2)-3,5-Pri2), that have eta6 arene coordination were synthesized by reduction of the corresponding metal halides. The complexes are thermally stable in contrast to the corresponding Cri complexes of benzene or toluene which decompose at ...

Syntheses of neutral 'buS2'-, 'S /and 'buS4'and of anionic buS: -complexes with various main group and transition metals are described. The complexes were prepared by reacting the neutral sulfur ligands or their alkali salts with the metal halide or alkoxide. The ligands coordinate to metal ions in normal as well as high oxidation states. No redox reactions occur in the latter case. The complex...

few novel cobalt(ii) and copper(ii) complexes [m(fmp)3]cl2, [m(fmp)(bpy)2]cl2,[m(fmp)(phen)2]cl2 and [m(fmp)(phen)(bpy)]cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,ir, electronic, epr, mass spectra and cyclic voltam...

A novel method of photoinduced synthesis of unsymmetrical diaryl selenides from triarylbismuthines and diaryl diselenides has been developed. Although the arylation reactions with triarylbismuthines are usually catalyzed by transition-metal complexes, the present arylation of diaryl diselenides with triarylbismuthines proceeds upon photoirradiation in the absence of transition-metal catalysts. ...

Transition metal complexes have emerged as promising candidates for applications in solid-state electroluminescent devices. These materials serve as multifunctional chromophores, into which electrons and holes can be injected, migrate and recombine to produce light emission. Their device characteristics are dominated by the presence of mobile ions that redistribute under an applied field and as...
