catena-Poly[(E)-4,4'-(ethane-1,2-di-yl)dipyridinium [[bis-(thio-cyanato-κN)ferrate(II)]-di-μ-thio-cyanato-κN:S;κS:N]].
In the crystal structure of the title compound, {(C(12)H(14)N(2))[Fe(NCS)(4)]}(n), the iron(II) cation is coordinated by four N-bonded and two S-bonded thio-cyanate anions in a distorted octa-hedral coordination mode. The asymmetric unit consists of half an iron(II) cation and half a protonated (E)-4,4'-(ethane-1,2-di-yl)dipyridinium dication, each located on a centre of inversion. In addition, there are two thio-cyanate anions in general positions. The crystal structure consists of Fe-(NCS)(2)-Fe chains in which each iron(II) cation is additionally coordinated by two terminal N-bonded thio-cyanate anions. Non-coordinating dipyridinium dications are present between the thiocyanatoferrate(II) chains and are connected to the anions via N-H⋯N and N-H⋯S hydrogen-bond interactions.
