Three new isostructural open-framework sulfides, (NH4) 5Ga4-SbS10 (1), (NH4) 4Ga4SbS9(OH) · H2O (2a), and (NH4)3Ga4SbS9-(H2O) · 2H2O (2b), were synthesized under basic hydrothermal conditions using ammonium hydroxide as the structure-directing agent. The structures feature a three-dimensional open framework comprised of adamantane [Ga4Q10]8- clusters linked with Sb3+ centers. The compounds are wide gap semiconductors, crystallize in the chiral space group P213, and represent a new structure type. They exhibit nonlinear optical properties.
