Crystal structure of μ3-tetra-thio-anti-monato-tris[(cyclam)zinc(II)] tetra-thio-anti-monate aceto-nitrile disolvate dihydrate showing Zn disorder over the cyclam ring planes (cyclam = 1,4,8,11-tetra-aza-cyclo-tetra-deca-ne).

Reaction of Zn(ClO4)2·6H2O with cyclam (cyclam = 1,4,8,11-tetra-aza-cyclo-tetra-decane, C10H24N4) and Na3SbS4 in an aceto-nitrile/water mixture led to the formation of crystals of the title compound, [Zn3(SbS4)(C10H24N4)3](SbS4)·2CH3CN·2H2O or [(Zn-cyclam)3(SbS4)2](H2O)2(aceto-nitrile)2. The set-up of the crystal structure is similar to that of [(Zn-cyclam)3(SbS4)2].8H2O reported recently [Danker et al. (2021 ▸). Dalton Trans. 50, 18107-18117]. The crystal structure of the title compound consists of three crystallographically independent ZnII cations (each disordered around centers of inversion), three centrosymmetric cyclam ligands, one SbS4 3- anion, one water and one aceto-nitrile mol-ecule occupying general positions. The aceto-nitrile mol-ecule is equally disordered over two sets of sites. Each Zn2+ cation is bound to four nitro-gen atoms of a cyclam ligand and one sulfur atom of the SbS4 3- anion within a distorted square-pyramidal coordination. The cation disorder of the [Zn(cyclam)]2+ complexes is discussed in detail and is also observed in other compounds, where identical ligands are located above and below the [Zn(cyclam)]2+ plane. In the title compound, the building units are arranged in layers parallel to the bc plane forming pores in which the aceto-nitrile solvate mol-ecules are located. Inter-molecular C-H⋯S hydrogen bonding links these units to the SbS4 3- anions. Between the layers, additional water solvate mol-ecules are present that act as acceptor and donor groups for inter-molecular N-H⋯O and O-H⋯S hydrogen bonding.
