四种无机-有机杂化化合物，分子式为 In2(IO3)6(H2O)(2,2'-bipy)·H2O (1), In2(IO3)6(H2O)(1,10-phen)·H2O (2) )，Ga(IO3)3(2,2'-bipy)·HIO3 (3) 和 Ga(IO3)3(1,10-phen)·H2O (4) 在 100 °C 下经过 7 天水热合成，随后用单晶 X 射线衍射表征。In/I/O 系统中的双齿二胺配体 2,2'-bipy 和 1,10-phen 产生化合物 In2(IO3)6(H2O)(2,2'-bipy)·H2O 和 In2( IO3)6(H2O)(1,10-phen)·H2O 在单斜空间群 P21/c 中结晶。在 Ga/I/O 系统中使用相同的双齿二胺配体，即 2,2'-bipy 和 1,10-phen，导致形成 Ga(IO3)3(2,2'-bipy)·HIO3 和 Ga (IO3)3(1,10-phen)·H2O 在单斜空间群 P21/n 中结晶。In2(IO3)6(H2O)(2,2'-bipy)·H2O 和 In2(IO3)6(H2O)(1,10-phen)·H2O 均具有二维层状结构，前者由[In(H2O)(IO3)5]2–簇和[In(IO3)(2,2'-bipy)]2+链组成，后者由[In(H2O)(IO3)5 ]2– 簇和 [In(IO3)(1,10-phen)]2+ 链。化合物 Ga(IO3)3(2,2'-bipy)·HIO3 是由 [IO3] 金字塔、[GaO4N2] 八面体和不同的 [I2O6] 单元构成的一维带状结构，具有有趣的左右螺旋链。化合物Ga(IO3)3(1,10-phen)·H2O具有一维链状结构，由[GaO4N2]八面体和[IO3]棱锥交替构成。通过比较研究这些化合物的光致发光特性，我们可以得出结论，光致发光起源于以配体为中心的π-π*跃迁。合成的产物通过粉末 X 射线衍射、热重分析、红外光谱、ICP 和元素分析进行了进一步表征。 (© Wiley-VCH Verlag GmbH & Co.

Hydrothermal Synthesis, Structural Characterisations, and Photoluminescence Properties of Four Inorganic-Organic Hybrid Compounds in the Indium/Gallium Iodate Family

Four inorganic-organic hybrid compounds with the formulae In2(IO3)6(H2O)(2,2′-bipy)·H2O (1), In2(IO3)6(H2O)(1,10-phen)·H2O (2), Ga(IO3)3(2,2′-bipy)·HIO3 (3) and Ga(IO3)3(1,10-phen)·H2O (4) were hydrothermally synthesised at 100 °C over 7 d and subsequently characterised by single-crystal X-ray diffraction. The bidentate diamine ligands 2,2′-bipy and 1,10-phen in the In/I/O system give rise to the compounds In2(IO3)6(H2O)(2,2′-bipy)·H2O and In2(IO3)6(H2O)(1,10-phen)·H2O which crystallise in the monoclinic space group P21/c. Using the same bidentate diamine ligands, namely 2,2′-bipy and 1,10-phen, in the Ga/I/O system led to the formationof Ga(IO3)3(2,2′-bipy)·HIO3 and Ga(IO3)3(1,10-phen)·H2O which crystallise in the monoclinic space group P21/n. Both, In2(IO3)6(H2O)(2,2′-bipy)·H2O and In2(IO3)6(H2O)(1,10-phen)·H2O possess 2D layered structures, with the former consisting of [In(H2O)(IO3)5]2– clusters and [In(IO3)(2,2′-bipy)]2+ chains and the latter consisting of [In(H2O)(IO3)5]2– clusters and [In(IO3)(1,10-phen)]2+ chains. Compound Ga(IO3)3(2,2′-bipy)·HIO3 is a 1D ribbon built up from [IO3] pyramids, [GaO4N2] octahedra and distinct [I2O6] units and featuring interesting left and right helical chains. Compound Ga(IO3)3(1,10-phen)·H2O has a 1D chain-like structure constructed from the alternation of [GaO4N2] octahedra and [IO3] pyramids. By comparatively studying the photoluminescence properties of these compounds, we may conclude that the photoluminescence originates from ligand-centred π-π* transitions. The synthesised products were further characterised by powder X-ray diffraction, thermogravimetric analysis, IR spectroscopy, ICP and elemental analysis.(© Wiley-VCH Verlag GmbH & Co.
