T. Akitsu and Y. Einaga

Abstract: In the title compound, [Cu(ClO₄)₂(C₃H₁₀N₂)₂], the Cu atom is located at a center of symmetry. Despite asymmetric introduction of N-methyl groups into the ethylenediamine moieties, a second-order Jahn-Teller effect produces a typical semi-coordination trans-[CuN₄(O₂)] environment with long axial Cu-O bonds of 2.569  (2)  Å. The Cu-N bond distances are 2.004  (2) and 2.057  (2)  Å.
