| This dissertation is composed of five parts as following:Part one: Review. The history, structure, classification and furtheropportunities of heteropoly compounds were reviewed in this part; The research state of heteropoly compounds of the certain new type polyoxometalatescontaining molybdenum ; Bicapped-Keggin structure ; Orginic-Inorganic Hybrids ;dualistic rare earth-mdybdenum was summarized.Part two: The heterpolychromomolybdenum(NH4)6[CrMo14O42](OH)12·12H2O·1.5 KBrO3 with Bicapped-Keggin structure was synthesized the first time . And it was characterized by elementaryanalysis,IR,X-ray diffraction ad UV-Vis spectra.Part three: A new type of Orginic-Inorganic HybridsNi(H2O)4(Gly)[Mo4O12(OH)2]·2H2O has been synthesized the first time and it was characterized by elementaryanalysis,IR,X-ray diffraction and UV-Vis spectra.Part four: In this paper, four heteropoly complexes with lanthanide K8H[LnMo12O42]·40H2O (Ln=La, Pr, Nd, Sm) were first synthesized and characterized by elementary analyses, chemical analyses, IR, UV, TG-DTA .Part five: In this chapter, we synthesised a new Anderson-type compound and characterized by infrared spectrum, UV, element analysis, ICP, X-ray powder pattern, thermal study (DTA), et al. Their general molecular formular is Na7[IW6O24]·8H2O. This new compound is an Anderson-type periodates.
