Three new isostructural open-framework sulfides, (NH(4))(5)Ga(4)SbS(10) (1), (NH(4))(4)Ga(4)SbS(9)(OH) x H(2)O (2a), and (NH(4))(3)Ga(4)SbS(9)(H(2)O) x 2 H(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(4)Q(10) clusters linked with Sb(3+) centers. The compounds are wide gap semiconductors, crystallize in the chiral space group P2(1)3, and represent a new structure type. They exhibit nonlinear optical properties.
三种新的同构开放式框架硫化物，(NH(4))(5)Ga(4)SbS(10) (1)、(NH(4))(4)Ga(4)SbS(9)(OH) x H(2)O (2a) 和(NH(4))(3)Ga(4)SbS(9)(H(2)O) x 2 H(2)O (2b)，是在碱性水热条件下使用氨水溶液作为结构导向剂合成的。这些结构的特点是由金刚烷Ga(4)Q(10)簇与 Sb(3+)中心连接而成的三维开放式框架。这些化合物是宽带隙半导体，结晶于手性空间群 P2(1)3 中，代表了一种新的结构类型。它们具有非线性光学性质。
