2C:N;1:2'2C:N-dicyano-1-2C-bis(ethylenediamine-22N,N')platinum(II)copper(II)], [CuPt(CN)4(C2H8N2)2]n, (I), consists of one-dimensional chains running along the [111] direction. Both Cu and Pt atoms are located on centres of symmetry in an alternating array of [Cu(en)2]2+ (en is ethylenediamine) and [Pt(CN)4]2- units. The Pt-C coordination bond distances of 1.985 (4) and 1.995 (4) Å are longer than those of an analogous NiII complex. Moreover, due to Jahn-Teller distortion, the axial Cu-N bond distance of 2.562 (5) Å is longer than the equatorial ones of 2.014 (4) and 2.017 (4) Å.
