摘要：

We present the first report of hexagonally ordered mesostructured ternary metal tin sulfide materials along with their structure and optical properties. The new mesophases designated as (CP)(x)MySn2S6 (M=Zn2+, Cd2+, Ga3+) where synthesized by linking [Sn2S6](4-) clusters with metal ions in the presence of cetylpyridinium (CP) surfactant molecules in formamide solution under basic conditions. The materials are semiconductors in the energy range 2.5 < E-g < 3.1 eV. The mesostructured (CP)(x)MySn2S6 show photoluminescence, when excited with light above the band gap.
