In the title complex, Cu(H(2)NCH(2)CH(2)NH(2))(3)(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.
在标题配合物Cu(H₂NCH₂CH₂NH₂)₃₂中，铜原子的环境为畸变八面体，由来自三个螯合乙二胺配体的六个氮原子构成。Cu—N键长范围为2.050 (2)至2.300 (2) Å。该配合物阳离子与两个三氟乙酸根阴离子通过弱N—H⋯O和N—H⋯F氢键相连，形成三维框架。在两个阴离子中，氟原子在两个位置上无序分布；在一个位置上，占位因子分别为0.55和0.45，在另一个位置上，其值分别为0.69和0.31。
