Using Zn(SPhMe-4)(2) as precursor, a new thermostable zinc sulfide superlattice [Zn-10(mu(3)-S)(4)(SPhMe-4)(12)(DMF)(4)] (1), was synthesized through diffusion method at room temperature. Compound 1 is built upon a neutral T3 supertetrahedral [Zn-10(mu(3)-S)(4)(SPhMe-4)(12)(DMF)(4)] cluster, which is assembled through weak interactions into a 3-dimensional body-centered cubic superlattice that is chemically stable and free of strong covalent coupling. The four DMF group were located at the tetrahedron corners of the T3 cluster in such a manner that both the local charge balance and global charge compensation could be satisfied. The UV-Vis diffuse reflectance spectrum shows that 1 is a wide-gap semiconductor with the band gap of 2.99 eV.
