A new three-dimensional indium phosphite,[In2(HPO3)4](NH3CH2CH2NH3),was prepared under hydrothermal conditions via using ethylenediamine as a template.Its structure was solved by singlecrys-tal X-ray diffraction.The compound crystallizes in a monoclinic system,space group P2/n,with cell parameters a=0.91405(5)nm,b=0.91984(5)nm,c=0.96120(5)nm,β=115.9950(10)°,V=0.72640(7)nm3,Z=2,R1=0.0249,wR2=0.0650,GOF=1.044.The inorganic topological structure is built up from the vertex linking of InO6 octahedral and HPO3 pyramidal tetrahedral units,forming eight-membered ring channels along the [506] direction.The diprontonated ethylenediamine molecules are entrapped in eight-membered ring channels.
A new three-dimensional indium phosphite, [In2 (HPO3) 4] (NH3CH2CH2NH3), was prepared under hydrothermal conditions via using ethylenediamine as a template. Its structure was solved by singlecrys-tal X-ray diffraction. The compound crystallizes in a monoclinic space group P2 / n with cell parameters a = 0.91405 (5) nm, b = 0.91984 (5) nm, c = 0.96120 (5) nm, β = 115.9950 (10) °, V = 0.72640 , Z = 2, R1 = 0.0249, wR2 = 0.0650, GOF = 1.044. The inorganic topological structure is built from the vertex linking of InO6 octahedral and HPO3 pyramidal tetrahedral units, forming eight-membered ring channels along the [506] direction. The diprontonated ethylenediamine molecules are entrapped in eight-membered ring channels.
