THERMAL-BEHAVIOR OF HETEROBIMETALLIC COMPOUNDS OF THE TYPE DPPFMCL(2), [DPPF=1,1-BIS(DIPHENYLPHOSPHINO)FERROCENE AND M=NI,PD,PT] IN AN OXIDIZING ATMOSPHERE AND CHARACTERIZATION OF THE FINAL DECOMPOSITION PRODUCTS
Ol. Casagrande et al., THERMAL-BEHAVIOR OF HETEROBIMETALLIC COMPOUNDS OF THE TYPE DPPFMCL(2), [DPPF=1,1-BIS(DIPHENYLPHOSPHINO)FERROCENE AND M=NI,PD,PT] IN AN OXIDIZING ATMOSPHERE AND CHARACTERIZATION OF THE FINAL DECOMPOSITION PRODUCTS, Polyhedron, 16(1), 1997, pp. 171-177
The thermal behaviour of dppf [dppf = 1,1bis(diphenylphosphino)ferroce
ne] and dppfMcl(2) [M = Ni, Pd, Pt] in dry air has been investigated b
y thermal analysis and the final decomposition products were character
ized by Rutherford backscattering spectrometry, infrared spectroscopy,
Mossbauer spectroscopy and X-ray powder diffractometry. Thermal decom
position mechanisms, the thermal stability as well as the composition
and final residues are influenced by the Mcl(2) fragments. The thermal
stability decreases in the order dppf > dppf-NiCl2 > dppfPtCl(2) > dp
pfPdCl(2). The analysis of the RES spectra of the final decomposition
products shows that the phosphorus atoms are not lost during the heati
ng, while all the chlorine has evolved as Cl-2 gas. The Mossbauer and
X-ray results show the formation of several iron phosphates besides ni
ckel metaphosphate, nickel oxide, metallic Pd and Pt. Copyright (C) 19
