Dinuclear dialkoxo-bridged cyclopentadienylsiloxo titanium complexes.
The dinuclear dialkoxo-bridged complexes [(TiCl)(2)(mu-O(2)L)(mu-{(eta(5)-C(5)Me(4)SiMeO)(2)(mu-O)})] (O(2)L = 1,2-O(2)C(2)H(4), 1,2-O(2)C(6)H(4), 1,2-(OCH(2))(2)C(6)H(4), O(2)SiPh(2)) were obtained by reaction of [(TiCl(2))(2)(mu-{(eta(5)-C(5)Me(4)SiMeO)(2)(mu-O)})] () with the corresponding dilithium salt () or diol (, , ). Alkylation of and with ClRMg afforded [(TiR)(2)(mu-O(2)L)(mu-{(eta(5)...
متن کاملBent dinuclear platinum(II) halo-bridged carbonyl complexes.
Crystals of trans-Pt₂(μ-X)₂X₂(CO)₂ (X = Br, I) have been grown and their molecular and crystalline structures have been solved by X-ray diffraction methods. In both cases the dinuclear molecules are bent, with a bending angle of 164.6° and 156.5° for the bromide and the iodide, respectively. While the structure of the bromo-derivative is reported here for the first time, a modification of trans...
متن کاملA novel route towards water-soluble luminescent iridium(iii) complexes via a hydroxy-bridged dinuclear precursor.
The synthesis and photophysical characterization of a new family of luminescent water-soluble ionic iridium(iii) complexes of the general formula [(ppy)2Ir(bpy)]X are reported. The Ir(iii) complexes incorporate a cyclometalated 2-phenylpyridine (ppy), the ancillary ligand 2,2'-bipyridyl (bpy) and different counterions (X- = EtO-, OH-, EtOCH2CO2-, MeOCH2CO2-). These complexes were obtained start...
متن کاملNew Insights into Structure and Luminescence of EuIII and SmIII Complexes of the 3,4,3-LI(1,2-HOPO) Ligand
We report the preparation and new insight into photophysical properties of luminescent hydroxypyridonate complexes [M(III)L](-) (M = Eu or Sm) of the versatile 3,4,3-LI(1,2-HOPO) ligand (L). We report the crystal structure of this ligand with Eu(III) as well as insights into the coordination behavior and geometry in solution by using magnetic circular dichroism. In addition TD-DFT calculations ...
متن کاملSynthesis, Spectroscopy and Magnetism of Alkoxobridged Dinuclear Copper(II) Complexes with 2 Amino Picolines as the Ligands
The synthesis, spectroscopic and magnetic characterization of a series of new alkoxo-bridged binuclear copper (II) compounds are described. All complexes have the general formula [Cu (m-OR)(L)2]2(ClO4)2 · x H2O, in which m-OR = CH3O-, C2H5O- or C3H7O-<e...
