Herein, we report the syntheses, spectral and structural characterization, and magnetic behavior of four new dinuclear terephthalato-bridged copper(II) complexes with formulae [Cu2(trpn)2(mu-tp)](ClO 4)2·2H2O (1), [Cu2(aepn) 2(mu-tp)(ClO4)2] (2), [Cu2(Medpt) 2(mu-tp)(H2O)2](ClO4)2 (3) and [Cu2(Et2dien)2(mu-tp)(H 2O)](ClO4)2 (4) where tp = terephthalate dianion, trpn = tris(3-aminopropyl)-amin, aepn = N-(2-aminoethyl)-1,3- propanediamine, Medpt = 3,3?-diamino-N-methyldipropylmine and Et 2dien = N,N-diethyldiethylenetriamine. The structures of these complexes consist of two mu-tp bridging Cu(II) centers in a bis(monodentate) bonding fashion. The coordination geometry of the Cu(II) ions in these compounds may be described as close to square-based pyramid (SP) with severe significant distortion towards trigonal bipyramid (TBP) stereochemistry in 1. The visible spectra of the complexes in aqueous solutions are in complete agreement with the assigned X-ray geometry around the Cu(II) centers. Also, the solid infrared spectral data for the stretching frequencies of the tp-carboxalato groups, the nu(COO-) reveals the existence of bis(monodentate) coordination mode for the bridged terephthalate ligand. The susceptibility measurements at variable temperature over the range 2-300 K are reported. Despite the same bonding mode of the tp bridging ligand, there has been observed slight antiferromagnetic coupling for the compounds 1 and 4 with J values of -0.5 and -2.9 cm3 K mol-1, respectively, and very weak ferromagnetic coupling for 2 and 3 with J values of 0.8 and 10.1 cm3 K mol-1, respectively. The magnetic results are discussed in relation to other related mu-terephthalato dinuclear Cu(II) published compounds.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 105-83-9 is helpful to your research. Electric Literature of 105-83-9
