Crystal structure of μ-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(ClO)·6HO with cyclam (cyclam = 1,4,8,11-tetra-aza-cyclo-tetra-decane, CHN) and NaSbS in an aceto-nitrile/water mixture led to the formation of crystals of the title compound, Zn(SbS)(CHN)·2CHCN·2HO or (Zn-cyclam)(SbS)(aceto-nitrile). The set-up of the crystal structure is similar to that of [(Zn-cyclam)(SbS)]8HO reported recently [Danker (2021 ▸). . , 18107-18117]. The crystal structure of the title compound consists of three crystallographically independent Zn cations (each disordered around centers of inversion), three centrosymmetric cyclam ligands, one SbS 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 Zn cation is bound to four nitro-gen atoms of a cyclam ligand and one sulfur atom of the SbS anion within a distorted square-pyramidal coordination. The cation disorder of the [Zn(cyclam)] complexes is discussed in detail and is also observed in other compounds, where identical ligands are located above and below the [Zn(cyclam)] plane. In the title compound, the building units are arranged in layers parallel to the 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 SbS 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.
