Synthesis and crystal structure of poly[[di-μ(3)-tetra­thio­anti­monato-tris­[(cyclam)cobalt(II)]] aceto­nitrile disolvate dihydrate] (cyclam = 1,4,8,11-tetra­aza­cyclo­tetra­deca­ne)

Reaction of Co(ClO(4))(2)·6H(2)O with cyclam (cyclam = 1,4,8,11-tetra­aza­cyclo­tetra­deca­ne) and Na(3)SbS(4)·9H(2)O (Schlippesches salt) in a mixture of aceto­nitrile and water leads to the formation of crystals of the title compound with the composition {[Co(3)(SbS(4))(2)(C(10)H(24)N(4))(3)]·2CH(3)CN·2H(2)O}( n ) or {[(Co-cyclam)(3)(SbS(4))(2)]·2(aceto­nitrile)·2H(2)O}( n ). The crystal structure of the title compound consists of three crystallographically independent [Co-cyclam](2+) cations, which are located on centers of inversion, one [SbS(4)](3−) anion, one water and one aceto­nitrile mol­ecule that occupy general positions. The aceto­nitrile mol­ecule is disordered over two orientations and was refined using a split model. The Co(II) cations are coordinated by four N atoms of the cyclam ligand and two trans-S atoms of the tetra­thio­anti­monate anion within slightly distorted octa­hedra. The unique [SbS(4)](3−) anion is coordinated to all three crystallographically independent Co(II) cations and this unit, with its symmetry-related counterparts, forms rings composed of six Co-cyclam cations and six tetra­thio­anti­monate anions that are further condensed into layers. These layers are perfectly stacked onto each other so that channels are formed in which acetontrile solvate mol­ecules that are hydrogen bonded to the anions are embedded. The water solvate mol­ecules are located between the layers and are connected to the cyclam ligands and the [SbS(4)](3−) anions via inter­molecular N—H⋯O and O—H⋯S hydrogen bonding.
