μ-Oxalato-k⁴ O ¹,O ²:O ^1′,O ^2′-bis-{[N,N′-bis(pyridin-2- ylmethylene)propane-1,2-diamine-k⁴-N,N′,N′′, N′′′]copper(II)} bis(perchlorate)

In the centrosymmetric dinuclear title complex, [Cu2(C2O4)(C15H16N4)2] (ClO4)2, each Cu^II ion is in an elongated octa-hedral environment, coordinated by two oxalate O atoms and four N atoms from the tetra-dentate ligand. One O atom and three N atoms are in the equatorial plane, and another O atom and one N atom are in axial sites. Each copper ion is bound to two O atoms from the two different carboxyl-ate groups of the oxalate ligands, with a Cu⋯Cu distance of 5.6623 (16) Å. The anions lie on twofold rotation axes.
