|Title:||Some Insights Into The Reactivity Of Oxovanadium Phosphate: Synthesis And Characterization Of An Vopo4-h2n(ch2) 3nh2 Coordination Compound|
|Author:||De Parias R.F.|
|Abstract:||The lamellar matrix of VOPO4·2H2O was used as the host species to prepare a VOPO4-1,3-diaminopropane coordination compound. The oxovanadium matrix and the synthesized hybrid were characterized by elemental analysis, infared spectroscopy, thermogravimetry, X-ray diffractometry and SEM microscopy. The elemental analysis results, as well as the X-ray diffraction patterns and quantum chemical calculations, strongly suggest that the synthesized matrix is an equimolar (1:1) mixture of two compounds with the formulas VOPO4·[H2N-(CH 2)3-NH2] and VOPO4·[H 2N-(CH2)3-NH2]0.5. The SEM micrographs obtained for the VOPO4- diaminopropane hybrid matrix show that the microstructure of VOPO4·2H2O is changed after reaction, with an overall exfoliation of the oxovanadium matrix.|
