{N,N′-Bis[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine-4 N,N′,N′′,N′′′}bis-(trifluoro-methane- sulfanato-κO)copper(II)

Abstract

A discrete neutral CuII complex, [Cu(CF3SO3)2(C16H18N4)], has been derived from the symmetrical tetra-dentate Schiff base, N,N′-bis-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine. The copper centre assumes a tetra-gonally distorted pseudo-octa-hedral geometry with the O atoms of two trifluoro-methane-sulfonate anions coordinated weakly in the axial positions. The Cu - N distances lie in the range 1.941 (3)-2.011 (3) Å and the Cu - O distances are 2.474 (3) and 2.564 (3) Å.
