Cd7I12S · 3H2O: A novel 3-D inorganic open-framework with unusual heptanuclear quasi-supertetrahedra

A novel 3-D inorganic open-framework containing unusual heptanuclear quasi-supertetrahedra, Cd7I12S · 3H2O (1), was obtained by hydrothermal reaction and structurally characterized. Optical absorption spectrum reveals that the presence of an optical gap of 2.26 eV, indicating that compound 1 is a semiconductor.

Graphical abstractA novel compound Cd7I12S · 3H2O, possessing an acentric nature that allows it to be a potential NLO property, has been synthesized via hydrothermal reaction. The crystal structure is characteristic of a 3-D inorganic open-framework, containing unusual heptanuclear quasi-supertetrahedra. Optical absorption spectrum shows that the title compound is a semiconductor.Figure optionsDownload full-size imageDownload as PowerPoint slide
