title: catena-Poly[(E)-4,4'-(ethene-1,2-di-yl)dipyridinium [[bis-(thio-cyanato-κN)ferrate(II)]-di-μ-thio-cyanato-κN:S;κS:N]].
abstract: In the title compound, {(C(12)H(12)N(2))[Fe(NCS)(4)]}(n), each Fe(II) cation is coordinated by four N-bonded and two S-bonded thio-cyanate anions in an octa-hedral coordination mode. The asymmetric unit consists of one Fe(II) cation, located on a center of inversion, as well as one protonated (E)-4,4'-(ethene-1,2-di-yl)dipyridinium dication and two thio-cyanate anions in general positions. The crystal structure consists of Fe-(NCS)(2)-Fe chains extending along the a axis, in which two further thio-cyanate anions are only terminally bonded via nitro-gen. Non-coordinating (E)-4,4'-(ethene-1,2-di-yl)dipyrid-inium cations are found between the chains.
