Systematic explorations of new phases in the A(I)-In(III)-I(V)-O system by hydrothermal reactions led to five new compounds, namely, AIn(IO(3))(4) (A = Li, Na), Rb(3)In(IO(3))(6) and A(2)HIn(IO(3))(6) (A = Rb, Cs). The structure of AIn(IO(3))(4) (A = Li, Na) contains one-dimensional In(IO(3))(4) chains separated by Li(+) or Na(+) cations. In both compounds, each In(3+) cation is octahedrally coordinated by six IO(3)(-) anions, neighboring In(3+) cations are interconnected by bidentate bridging iodate anions into 1D chains. The structures of Rb(3)In(IO(3))(6) and A(2)HIn(IO(3))(6) (A = Rb, Cs) all feature isolated In(IO(3))(6) anions with alkali metal ions (and H(+) ions) as spacers. Both optical diffuse reflectance spectrum measurements and band structure calculations based on DFT methods indicate that LiIn(IO(3))(4), NaIn(IO(3))(4), and Rb(2)HIn(IO(3))(6) are insulators.
通过水热反应对 A(I)-In(III)-I(V)-O 体系中的新相进行系统探索，得到了五个新化合物，分别为 AIn(IO(3))(4)（A = Li，Na）、Rb(3)In(IO(3))(6)和 A(2)HIn(IO(3))(6)（A = Rb，Cs）。AIn(IO(3))(4)（A = Li，Na）的结构包含一维In(IO(3))(4)链，由 Li(+)或 Na(+)阳离子隔开。在这两种化合物中，每个 In(3+)阳离子均被六个 IO(3)(-)阴离子六配位，相邻的 In(3+)阳离子通过桥联碘酸根阴离子连接成一维链。Rb(3)In(IO(3))(6)和 A(2)HIn(IO(3))(6)（A = Rb，Cs）的结构均为孤立的In(IO(3))(6)阴离子，由碱金属离子（和 H(+)离子）作为间隔物。基于 DFT 方法的光学漫反射光谱测量和能带结构计算均表明 LiIn(IO(3))(4)、NaIn(IO(3))(4)和 Rb(2)HIn(IO(3))(6)是绝缘体。
