| Polyoxometalates (POMs), as a rich class of inorganic metal-oxide cluster compounds, have large numbers of structural diversity and various applications in different areas, including optics,magnetism, catalysis,medicine, and biology.The aim of this thesis is to use N-heterocycle ligands to react with in-situ generated polymolybdate anion to construct new polymolybdate derivative ,investigate the synthetic conditions (such as pH,counterion and concentration )and rules for the new compounds and explore the relationships between structures and properties for the new compounds.Two new polymolybdate compounds have been synthesized via convenient aqueous solution synthesis methods. These new complexes were structurally characterized by single crystal X-ray diffractions ,elemental analyses ,IR, UV, and TG and.1. In aqueous phase,a polymolybdate derivatives were synthesized by using morpholine as organic ligands: Na3 [(C4H9NO) (C4H10NO)] (Mo8O26)?2H2O (1)2. In aqueous phase, Choosing Na2MoO4·2H2O and NaVO3·H2O as the starting materials, obtain a new polyoxomolybdovanadate cluster : (C4H10NO)3 (H3O)7?[V2Mo16O58]?2H2O (2)... |
