Some insights into the reactivity of oxovanadium phosphate: synthesis and characterization of an VOPO4–H2N(CH2)3NH2 coordination compound [PDF]
Journal of the Serbian Chemical Society, 2005 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,
