Hydrothermal Synthesis and Characterization of a Novel Organic Inorganic Hybrid Compound Co(dien)_2(dienH_3)(H_3O)_7P_2Mo_5O_(23)_2·14H_2O

摘要

A new compound,[Co(dien)2](dienH3)(H3O)7[P2Mo5O23]2·14H2O, has been hydrothermallly synthesized by using Na2MoO4,CoCl2, H3PO4 and dien, and structurally characterized by elemental analysis, X-ray powder diffraction analysis, SEM, IR and TG analysis. The results show that the compound is composed of a polyanion [P2Mo5O23]212- , complex [Co(dien)2]2+ cation, protonated [dienH3]3+ , and forteen crystallization water molecule.
