[μ-2,8-Dimethyl-5,11-bis(dimethyl­amino­ethyl)-1,4,5,6,7,10,11,12-octahydro­diimidazo[4,5-h;4,5-c][1,6]diazecine]bis[aqua­copper(II)] diacetate hexahydrate

In the title compound, [Cu₂(C₂H₃O₂)₂(C₂₀H₃₆N₈)(H₂O)₂](C₂H₃O₂)₂·6H₂O, the dinuclear cation has inversion symmetry and contains square-pyramidal Cu^II ions separated by 7.471 (1) Å. Symmetry-related cations are linked to a framework of rings of five water molecules, where each water molecule acts as both a single hydrogen-bond donor and acceptor, an arrangement very close to that believed to exist in liquid water.
