The synthesis and the crystal structures of the complexes [Cu(L I ) 2 ](ClO 4 ) ( 1 ) and [Cu(L I )(CH 3 CN) 2 (ClO 4 ) 2 ] ( 2 ) are reported. 1 crystallizes in the monoclinic space group C 2/c with the unit cell dimensions a = 13.169(4), b = 12.289(3), c = 14.732(3) Å, β = 109.03(2)° and Z = 4. Copper(I) is coordinated to four N atoms of the two 1,10‐Phenanthroline‐5,6‐dione (L I ) ligands with a two‐fold axis passing between the ligands. The copper(II) compound 2 crystallizes in the orthorhombic space group P bn2 1 with unit cell dimensions of a = 7.498(5), b = 23.492(7), c = 12.363(4) Å and Z = 4. Copper(II) coordination can be described as a distorted octahedron with the N donor atoms of one L I ligand and of two molecules of CH 3 CN occupying the equatorial positions completed by two oxygen atoms of the two perchlorate molecules in the axial positions.
