Synthesis and crystal structure of catena-poly[[bis[(2,2 ′ ;6 ′ ,2 ′ ′ -terpyridine)manganese(II)]- μ 4-pentathiodiantimonato] tetrahydrate] showing a 1D MnSbS network

The asymmetric unit of the title compound, {[Mn2Sb2S5(C15H11N3)2] · 4H2O}n, consists of two crystallographically independent MnII ions, two unique terpyridine ligands, one [Sb2S5]4 − anion and four solvent water molecules, all of which are located in general positions. The [Sb2S5]4 − anion consists of two SbS3 units that share common corners. Each of the MnII ions is fivefold coordinated by two symmetry-related S atoms of [Sb2S5]4 − anions and three N atoms of a terpyridine ligand within an irregular coordination. Each two anions are linked by two [Mn(terpyridine)]2+ cations into chains along the c-axis direction that consist of eight-membered Mn2Sb2S4 rings. These chains are further connected into a three-dimensional network by intermolecular O — H...O and O — H...S hydrogen bonds. The crystal investigated was twinned and therefore, a twin refinement using data in HKLF-5 [Sheldrick (2015). Acta Cryst. C71, 3 – 8] format was performed.
