Bis(ethylenediamine-²N,N')copper(II) 9,10-dioxoanthracene-2,6-disulfonate

Z.-X. Lian and H.-H. Li

Abstract: In the title compound, [Cu(C₂H₈N₂)₂](C₁₄H₆O₈S₂), the Cu^II atom lies on an inversion centre and is coordinated by two ethylenediamine ligands in a square-planar geometry. 9,10-Dioxoanthracene-2,6-disulfonate anions, also lying on inversion centres, coordinate weakly to Cu^II and accept N-HO hydrogen bonds from ethylenediamine, linking the [Cu(C₂H₈N₂)₂]²⁺ cations into chains. Adjacent chains are linked into extended two-dimensional networks via N-HO hydrogen bonds.
