Structural, electrochemical, and spectroscopic investigation of acetate bridged dinuclear tetrakis-Schiff base macrocycles of Mn and Zn.
The synthesis of Mn2LAc+, Zn2LAc+, and H4L2+ is described, where L is a tetrakis-Schiff base macrocycle formed using 4-tert-butyl-2,6-diformylphenol and 2,2′-diamino-N-methyldiethylamine resulting in an N6O2 coordination environment. In Mn2LAc+ and Zn2LAc+, the two metal centers are bridged by an acetate ligand. [Mn2LAc](ClO4)·(DMF)0.5, [Mn2LAc](ClO4)·(ACN)0.5, and [Zn2LAc](PF6) crystallized in...
متن کامل(dmit) and its dinuclear Ni(II) complex: spectroscopic and structural characterization
The optical properties of the dmit ion (dmits4,5-dimercapto-1,3-dithiol-2-thiolate) have been characterized under a range of conditions. The oxidatively sensitive anion is highly solvatochromic: lmaxs504 (H2O), 514 (MeOH), 568 (MeCN), and 632 nm (DMF). With a shift in absorption maximum of 4000 cm (DMF versus H2O), dmit 2y is possibly the most solvatochromic species known. The dianion is monopr...
متن کاملNew Dinuclear Methoxo-Bridged Manganese(III) complex: Synthesis, Characterization and Usage as New Precursor for Synthesis of Mn2O3 Particles
New dinuclear methoxo-bridged manganese(III) complex [Mn2((MeO-bph)en)2Cl2(m-CH3O)2] (1) was synthesized by template reaction of 2-hydroxy-4-methoxybenzophenone, 1,2-ethanediamine and MnCl2×6H2O with molar ration (1:1:1) in methanol as solvent. The title compound 1 was characterized by...
متن کاملDinuclear 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)...
