title: catena-Poly[[bis-(N-ethyl-ethylene-di-amine-κN,N')copper(II)]-μ-cyanido-κN:C-[dicyanido-κC-palladium(II)]-μ-cyanido-κC:N].
abstract: The title compound, [CuPd(CN)(4)(C(4)H(12)N(2))(2)](n), consists of one-dimensional chains. The Cu and Pd atoms are both located on centers of symmetry in an alternating array of [Cu(N-Eten)(2)](2+) (N-Eten = N-ethyl-ethylenediamine) and [Pd(CN)(4)](2-) units. The Pd-C distances of 1.991 (3) and 1.992 (3) Å are inter-mediate values compared with the analogous Ni(II) and Pt(II) complexes [Akitsu & Einaga (2007 ▶). Inorg. Chim. Acta, 360, 497-505]. Due to Jahn-Teller effects, the axial Cu-N bond distance of 2.548 (2) Å is noticeably longer than the equatorial distances [Cu-NH(2) = 2.007 (2) and Cu-NHC(2)H(5) = 2.050 (2) Å]. There are interchain hybrogen bonds, with N(-H)⋯N = 3.099(4) Å.
