Abstract: In the title complex, [Cu(H₂NCH₂CH₂NH₂)₃](CF₃COO)₂, the environment of the Cu atom is distorted octahedral, 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 trifluoroacetate anions are connected by weak N-HO and N-HF 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.
