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—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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
