Synthesis, structure, and transformation studies in a family of inorganic-organic hybrid framework structures based on indium.

摘要: Eight new open-framework inorganic-organic hybrid compounds based on indium have been synthesized employing hydrothermal methods. All of the InO6, C2O4, and HPO3/HPO4/SO4 units connected to form structures different dimensionality Thus, zero- (I), two- (II, III, IV, V, VII, VIII), three-dimensionally (VI) extended networks. The formation first zero-dimensional compound is noteworthy In addition, concomitant polymorphic observed in present study. molecular compound, I, was found be reactive, transformation studies presence a base (pyridine) give rise II while addition an acid (H3PO3) gives phosphite with pillared layer structure (T1). Preliminary density functional theory calculations suggest that stabilities polymorphs are different, one forms (II) being preferred over other, which consistent experimental behavior. oxalate perform more than role structures. connect two centers satisfy coordination requirements as well achieve charge balance II, VI. terminal V possibility intermediate Both in-plane out-of-plane connectivity were 31 characterized by powder X-ray diffraction, IR spectroscopy, thermogravimetric analysis, P-31 NMR studies.
