| 摘 要： | The first primary organicamine templated indium iodate with the formula (H2en)KIn(IO3)6·2(H2O) was hydrothermally synthesized via reaction at 100 °C for 7 d and characterized by single-crystal X-ray diffraction and thermal analysis. The compound crystallized in a triclinic system with space group P1, a=0.69803(14) nm, b=0.70863(14) nm, c=1.2091(2) nm, α=76.417(4)°, β=79.953(4)°, γ=72.206(3)°, V=0.55012(19) nm3. Structure determination indicates that it is made up of zero-dimensional units each of which consists of In(IO3)6]3-anion, potassium, water and ethylenediamine cation. The most striking feature of the compound is that it possesses helical hydrogen bonds formed by organic amine template, water molecules and inorganic network.
