    Abstract

    The cluster compounds K 10 Zn 4 Sn 4 S 17 , K 10 Mn 4 Sn 4 S 17 , K 10 Fe 4 Sn 4 S 17 , K 10 Co 4 Sn 4 S 17 , Cs 10 Cd 4 Sn 4 S 17 and K 10 Zn 4 Ge 4 S 17 are described. The structures of these compounds, refined by single-crystal X-ray diffraction techniques, contain the discrete cluster [M 4 M′ 4 S 17 ] 10- (M = Zn, Mn, Co, Fe, Cd; M′ = Sn or Ge) which has the structure of Si 8 C 17 H 36 . It is built from the sulfur-connected tetrahedral SnS 4 and MS 4 units with the additional quadruply bridging sulfur atom at the center of the cluster. All compound show some solubility and stability in water and formamide. Cs 10 Cd 4 Sn 4 S 17 and K 10 Zn 4 Ge 4 S 17 show photoluminescence at room temperature.The magnetic properties of K 10 Mn 4 Sn 4 S 17 , K 10 Fe 4 Sn 4 S 17 , K 10 Co 4 Sn 4 S 17 indicate strong antiferromagnetic interactions arising from spin coupling within the cluster but their magnetic susceptibility is characterized with a discrepancy between field-cooled and zero field-cooled measurements.
