X-ray structure and photoluminescence of copper(I) 2,6-bis(trifluoromethyl)benzoate
摘要:
This report describes synthesis, X-ray crystallographic characterization, and photoluminescence of copper(I) 2,6-bis(trifluoromethyl)benzoate, [Cu(O2C(2,6-CF3)(2)C6H3)] (1). Complex 1 has a polymeric structure comprised of axially bound dinuclear [Cu-2(O2C(2,6-CF3)(2)C6H3)(2)] units that is reminiscent of the well-known structure of copper(I) acetate, [Cu-2(O2CMe)(2)] (2). However, a close comparison of two analogues revealed a non-planarity of 1D chains and their orthogonal disposition in the crystal structure of 1 versus parallel alignment of planar chains in 2. Complex 1 exhibits green photoluminescence at ca. 560 nin upon UV-radiation (lambda(ex) = 350 mn) in the solid state. (c) 2007 Elsevier B.V. All rights reserved.
