Two new inorganic-organic hybrid polymers, Mn(QS)(H2O) (1) and Co(QS)(H2O)2 (2) (H2QS=8-hydroxyl-quinoline-5-sulfonic acid), based on 8-hydroxylquinoline-5-sulfonate ligand, have been synthesized under solvothermal conditions and their structures were solved by single-crystal X-ray diffraction analysis. Compound 1 is a three-dimensional open framework with rutile topology structure, and compound 2 is a three-dimensional supramolecular structure. These compounds were characterized by powder XRD, infrared spectroscopy, thermogravimetric analysis, fluorescence properties and magnetism properties.

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.
