Summary The crystal structure of bis(thiourea)iron(II) thiocyanate, Fe[SC(NH2)2]2(NCS)2, has been determined and refined by three-dimensional x-ray analysis. The complex crystallizes in the triclinic system, space group P −1, witha = 10.114(6),b = 7.662(8),c = 3.897(10) Å, α = 105.0(2)°, β = 81.8(3)°, γ= 96.4(3)° andz = 1. It is isostructural with M(tu)2(NCS)2, where M = Mn, Co or Ni and to = thiourea. The iron atom is located on a centre of symmetry and is coordinated to four planar sulfur atoms of the thiourea ligands (Fe-S 2.61 and 2.65 Å) and two nitrogen atoms of the thiocyanate groups (Fe-N 2.05 Å) in a distorted octahedral way. These octahedra are linked in chains with each thionilic sulfur atom shared by two adjacent iron atoms; magnetic measurements, Mössbauer and spectroscopic data are consistent with this polymeric structure.
