Fl. Alencar et al., Synthesis and properties of addition compounds between triphenylphosphine-oxide(TPPO) and lanthanide trifluoromethanesulfonates, J COORD CH, 46(4), 1999, pp. 471-478
Additon compounds between triphenylphosphine-oxide and trifluoromethanesulf
onates are synthesized and characterized by microanalyses, electrolytic con
ductance, vibrational (infrared) spectra, absorption spectra in the visible
region and thermogravimetric procedures. The results are in agreement with
the formulas La(CF3SO3)(3).3TPPO . 4H(2)O and Ln(CF3SO3)(3).4TPPO. The lig
ands (TPPO) coordinate through the phosphoryl oxygen. Complex interactions
with solvents of different donating capacities are also found. Thermogravim
etric studies result in lanthanide trifluoride products.
