title: Tris(ethane-1,2-diamine)copper(II) bis-(trifluoro-acetate).
abstract: In the title complex, [Cu(H(2)NCH(2)CH(2)NH(2))(3)](CF(3)COO)(2), the environment of the Cu atom is distorted octa-hedral, formed by six N atoms from three chelating ethane-1,2-diamine ligands. The Cu-N distances range from 2.050 (2) to 2.300 (2) Å. This complex cation and the two trifluoro-acetate anions are connected by weak N-H⋯O and N-H⋯F hydrogen bonds, forming a three-dimensional framework. In both anions, the F atoms are disordered over two positions; in one the site-occupancy factors are 0.55 and 0.45, in the other the values are 0.69 and 0.31.
