The mononuclear species 2,3 and 4 were characterized by elemental analysis, infrared spectroscopy, NMR and thermogravimetric analysis. The IR spectra show bands which are consistent with terminal monodentate nitrate group for 2-3 and ionic nitrate for 4. The 1H and 13C NMR data confirm that coordination of the organic ligands has occurred and the 31P{1H} NMR data for 4 clearly evidences the occurrence in solution of three cyclopalladated species with the dppf acting as a bridging ligand in two cases and as a chelate in one. The thermal behavior of compounds 1-4 suggests that complex 2 is the most stable. The X-ray diffractometry results show the formation of PdO from 1 and 2, Pd2OSO4 from 3, and of a mixture of PdO and Fe 2(PO4)3 from 4, as final decomposition products.764-770engCyclopalladated speciesIR and NMR spectroscopyThermogravimetric analysis1,1' bis(diphenylphosphine)ferrocene3,5 dimethylpyrazolecationferrocene derivativeligandnitric acid derivativepalladium complexpyrazole derivativequinolinethiolthiol derivativeunclassified drugcarbon nuclear magnetic resonancechemical analysischemical structureinfrared spectroscopynuclear magnetic resonanceprecursorproton nuclear magnetic resonancereaction analysisspectroscopystructure analysisthermal analysisthermogravimetryX ray diffractionArtigo10.1590/S0103-50532003000500011S0103-50532003000500011WOS:000185814100010Acesso aberto2-s2.0-02424903112-s2.0-0242490311.pdf3300223970814448
