Syntheses and Characterizations of Two New Organic-inorganic Hybrids Based on Heteropolymolybdates and Piperidine Molecules

摘要

Two new organic-inorganic compounds [(CH2)5NH2]3[PMo12O40]?3[(CH2)5NH] 1 and [(CH2)5NH2]6[P2Mo18O62]?5H2O 2 have been synthesized using conventional and hydrothermal methods, respectively, and characterized by elemental analyses, IR, TG and single-crystal X-ray diffraction. X-ray analyses show that in these compounds heteropolymolybdates [PMo12O40]3– and [P2Mo18O62]6– are reserved their Keggin or Dawson structures and linked to piperidine through electrostatic and hydrogen-bonding interactions.
