Three-dimensional frameworks of cubic (NH{sub 4}){sub 5}Ga{sub 4}SbS{sub 10}, (NH{sub 4}){sub 4}Ga{sub 4}SbS{sub 9}(OH) {small _bullet} H{sub 2}O, and (NH{sub 4}){sub 3}Ga{sub 4}SbS{sub 9}(OH{sub 2}) {small_bullet} 2H{sub 2}O.

Three new isostructural open-framework sulfides, (NH{sub 4}){sub 5}Ga{sub 4}SbS{sub 10} (1), (NH{sub 4}){sub 4}Ga{sub 4}SbS{sub 9}(OH) {sm_bullet} H{sub 2}O (2a), and (NH{sub 4}){sub 3}Ga{sub 4}SbS{sub 9}(H{sub 2}O) {sm_bullet} 2H{sub 2}O (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 [Ga{sub 4}Q{sub 10}]{sup 8-} clusters linked with Sb{sup 3+} centers. The compounds are wide gap semiconductors, crystallize in the chiral space group P2{sub 1}3, and represent a new structure type. They exhibit nonlinear optical properties.
