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

A discrete neutral Cu(II) complex, [Cu(CF(3)SO(3))(2)(C(16)H(18)N(4))], 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.
