SĂntesis de heteropolicompuestos hĂbridos con fĂłrmula [(CâHâ )âP] Hâ[(Al,Cr)MoâOââ(OH)â]â7HâO
Los [(CâHâ
)âP] Hâ[CrMoâOââ(OH)â]â7HâO, [(CâHâ
)âP] Hâ[(AlMoâOââ(OH)â]â7HâO, son heteropolicompuestos que fueron sĂntetizados, estudiados y caracterizados mediante espectrometrĂa de masas, anĂĄlisis por difracciĂłn de rayos X, espectroscopia de IR, anĂĄlisis termogravimĂ©trico y termogravimĂ©trico Diferencial (ATG y DTG). Se determinaron los parĂĄmetros de celda unitaria y se calcularon los nĂșmeros de fĂłrmulas unitarias. Se propusieron esquemas de descomposiciĂłn tĂ©rmica de los heteropolimolibdometalatos de trifenilfosfonio sintetizados.The [(CâHâ
)âP] Hâ[CrMoâOââ(OH)â]â7HâO, [(CâHâ
)âP] Hâ[(AlMoâOââ(OH)â]â7HâO are heteropoly compounds were synthesized, studied and characterized by mass spectrometry, X-ray diffraction, IR spectroscopic, thermogravimetric and differential thermogravimetric analysis (ATG and DTG). Unit cell parameters were determined, and unit formula numbers were calculated. Thermal decomposition schemes of the synthesized triphenylphosphonium heteropolymolybdometalates were proposed
