Synthesis, characterization, and structures of copper(I) complexes with N,N′-bis[1-(4-chlorophenyl)ethylidene]ethane-1,2-diamine and N,N′-bis[1-(4-nitrophenyl)ethylidene]ethane-1,2-diamine

摘要

Two ligands, N,N′-bis[1-(4-chlorophenyl)ethylidene]ethane-1,2-diamine (L1 ) and N,N′-bis- [1-(4-nitrophenyl)ethylidene]ethane-1,2-diamine (L2 ) and their corresponding copper(I) complexes, [Cu(L 1)₂]ClO₄ (1) and [Cu(L 2)₂]ClO₄ (2), have been synthesized and characterized by CHN analyses, 1H-NMR, IR, and UV-Vis spectroscopy. The crystal structures of L1 and [Cu(L 1)₂]ClO₄ (1) were determined from single crystal X-ray diffraction. L1 lies across a crystallographic inversion center and the C=N is approximately coplanar with the benzene ring and adopts E configuration. The coordination polyhedron about copper(I) in 1 is best described as a distorted tetrahedron. Quasireversible redox behavior is observed for the complexes.View full textDownload full textKeywordsAcetophenone derivatives, Diimine ligands, Copper(I) complexes, Distorted tetrahedral structureRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00958970902954110
