Tris(1,10-phenanthroline)copper(II) tricyanomethanide

I. Potocnák, M. Pohlová, C. Wagner and L. Jäger

Abstract: The crystal structure of [Cu(C₁₂H₈N₂)₃][C(CN)₃]₂ is composed of discrete [Cu(phen)₃]²⁺ cations (phen is 1,10-phenanthroline) and [C(CN)₃]^- anions. The Cu^II atom is octahedrally coordinated by the three phen ligands. As a consequence of the Jahn-Teller effect, the two axial Cu-N bonds of 2.219  (3) and 2.238  (3)  Å are longer than the equatorial Cu-N bonds, which are in trans positions, paired in two couples of almost equal distance [2.066  (3)/2.050  (3) and 2.121  (3)/2.121  (3)  Å].
