Diaquabis(ethylenediamine-²N,N')copper(II) bis(4-aminonaphthalene-1-sulfonate) dihydrate

M.-T. Li, C.-G. Wang, Y. Wu and X.-C. Fu

Abstract: In the title compound, [Cu(C₂H₈N₂)₂(H₂O)₂](C₁₀H₈NO₃S)₂·2H₂O, the Cu^II complex cation, located on an inversion centre, has a distorted octahedral coordination geometry formed by two ethylenediamine and two water molecules. The distance of 3.4987 (11) Å between the centroids of neighbouring parallel aromatic rings of aminonaphthalenesulfonate anions suggests the existence of [pi] - [pi] stacking.
