catena-Poly[[bis­(thio­cyanato-κN)cobalt(II)]-di-μ-thio­urea-κ(4) S:S]

In the title polymeric complex, [Co(NCS)(2){SC(NH(2))(2)}(2)](n), the asymmetric unit comprises a Co(II) ion, which is situated on an inversion centre, an N-bound thio­cyanate anion and a μ(2)-bridging thio­urea mol­ecule. The Co(II) atom is coordinated in a distorted octa­hedral fashion within an N(2)S(4) donor set. The bridging thio­urea ligands link Co(II) ions into a polymeric chain extending along [100]. The mol­ecular conformation is stabilized by intra­molecular N—H⋯N hydrogen bonds, which generate S(6) ring motifs. The crystal packing is stabilized by N—H⋯S inter­actions, which connect the chains into a three-dimensional architecture.
