μ-Cyanido-κ(2) C:N-dicyanido-κ(2) C-bis-(N-ethyl-ethylenedi-amine-κ(2) N,N')copper(II)copper(I).
In the title complex, [Cu(I)Cu(II)(CN)3(C4H12N2)2], the Cu(I) and Cu(II) ions and a bridging cyanide group lie on a twofold rotation axis. The Cu(II) ion is in a slightly-distorted square-pyramidal coordination environment, with the N atoms of the two symmetry-related N-ethyl-ethylenedi-amine ligands occupying the basal positions and an N-bonded cyanide group in the apical position. The Cu(I) ion is in a trigonal-planar coordination environment, bonded to the C atom of the bridging cyanide group and to two terminal cyanide groups. In the crystal, N-H⋯N hydrogen bonds involving two of the symmetry-unique N-H groups of the N-ethyl-ethylenedi-amine ligands and the N atoms of the terminal cyanide ligands link the mol-ecules into strands along [010].
