The title compound, poly[[tetracyano-octa-μ-cyano-hexakis-(N- ethylethylenediamine)tricopper(II)dicobaltate(III)] tetrahydrate], [Cu(C 4H12N2)2]3[Co(CN) 6]2·4H2O or {[Cu3Co 2-(CN)12(C4H12N2) 6]·4H2O}n, was crystallized from an aqueous reaction mixture containing Cu(ClO4)2, N-ethylethylenediamine and K3[Co(CN)6] in a self-assembling process. The polymeric chains are extended through -Co III-CN-CuII-linkages involving four or two cyanide ligands of the centrosymmetric [Co(CN)6]3- complex ions, forming a two-dimensional ladder structure. The CuII atoms, one of which also lies on an inversion centre, have a distorted octahedral coordination geometry, the degree of tetragonal Jahn-Teller distortion being T = 0.785 and 0.810 (T is the ratio of mean inplane Cu - N bond lengths to axial Cu - N bond lengths). This local Jahn-Teller distortion results from the anisotropic features of this two-dimensional cyano-bridged structure.
