K10M4Sn4S17 (M = Mn, Fe, Co, Zn): Soluble quaternary sulfides with the discrete [M4Sn4S17](10-)supertetrahedral clusters
Four cubic compounds are reported that contain the supertetrahedral cluster [M4Sn4S17](10-) where M = Mn, Fe, Co, Zn. The cluster features a central quadruply bridging sulfide ion (mu(4)-S) that holds together four divalent M atoms in a tetrahedral arrangement. This core is capped with four tridentate [SnS4](4-) fragments to complete the structure.
