Crystal structure of μ 3 -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 4 ) 2 ·6H 2 O with cyclam (cyclam = 1,4,8,11-tetra-aza-cyclo-tetra-decane, C 10 H 24 N 4 ) and Na 3 SbS 4 in an aceto-nitrile/water mixture led to the formation of crystals of the title compound, [Zn 3 (SbS 4 )(C 10 H 24 N 4 ) 3 ](SbS 4 )·2CH 3 CN·2H 2 O or [(Zn-cyclam) 3 (SbS 4 ) 2 ](H 2 O) 2 (aceto-nitrile) 2 . The set-up of the crystal structure is similar to that of [(Zn-cyclam) 3 (SbS 4 ) 2 ] . 8H 2 O reported recently [Danker et al. (2021 ▸). Dalton Trans . 50 , 18107-18117]. The crystal structure of the title compound consists of three crystallographically independent Zn II cations (each disordered around centers of inversion), three centrosymmetric cyclam ligands, one SbS 4 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 Zn 2+ cation is bound to four nitro-gen atoms of a cyclam ligand and one sulfur atom of the SbS 4 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 SbS 4 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.
