    Temperature dependent rate constants for the reactions of gas phase lanthanides with N2O
    摘要:
    The reactivity of gas phase lanthanide (Ln) atoms (Ln=La–Yb with the exception of Pm) with N2O from 298 to 623 K is reported. Lanthanide atoms were produced by the photodissociation of Ln(TMHD)3 (TMHD=2,2,6,6-tetramethyl-3,5-heptanato ion) and detected by laser-induced fluorescence. Large variations in the reaction rate constants are observed. The bimolecular rate constants are described in Arrhenius form by k[Ce(1G4)]=(1.9±0.5)×10−10 exp(−0.8±0.8 kJ mol−1/RT); Pr(4I9/2), (3.6±1.2)×10−10 exp(−8.0±1.2 kJ mol−1/RT); Nd(5I4), (3.4±0.4)×10−10 exp(−8.8±0.5 kJ mol−1/RT); Sm(7F0), (3.2±1.1)×10−10 exp(−11.2±1.2 kJ mol−1/RT); Eu(8S7/2), (2.7±0.4)±10−10 exp(−12.7±0.5 kJ mol−1/RT); Gd(9D2), (2.0±0.3)×10−10 exp(−6.4±0.5 kJ mol−1/RT); Tb(6H15/2), (2.9±0.5)×10−10 exp(−10.9±0.6 kJ mol−1/RT); Dy(5I8), (3.4±0.8)×10−10 exp(−16.2±0.8 kJ mol−1/RT); Ho(4I15/2), (2.9±0.5)×10−10 exp(−17.1±0.6 kJ mol−1/RT); Er(3H6), (3.3±1.2)×10−10 exp(−18.4±1.2 kJ mol−1/RT); Tm(2F7/2), (3.5±0.6)×10−10 exp(−19.5±0.6 kJ mol−1/RT); Yb(1S0), (2.5±0.2)×10−10 exp(−20.2±0.3 kJ mol−1/RT) where the uncertainties represent ±2σ. The reaction barriers are found to correlate to the energy required to promote an electron out of the 6s subshell.

    日期:1975.10
    The mixed ligand complexes, tris(dipivaloylmethanato) pyrazinates of trivalent lanthanide (except Ce, Pm and Lu) and yttrium ions were synthesised and characterised by elemental analyses, melting points, thermogravimetric analyses, magnetic moments, molar conductances and i.r. spectrum. The complexes are Ln(dpm)3Pz where Ln = trivalent lanthanide or yttrium ion, dpm = dipivaloylmethane and Pz = pyrazine

  • Enthalpies of adduct formation of some tris(dipivaloylmethanato)lanthanide complexes with 1,8-naphthyridine and bipyridyl
    作者:D.R. Dakternieks

    日期:1976.1
    Enthalpy data are reported for the addition of bipyridyl and 1,8-napthyridine to a series of tris(dipivaloylmethanato) lanthanide complexes, [(CH3)3CCOCHCOC(CH3)3]3Ln, in benzene solution at 25°C. In all cases the reactions are exothermic and only 1:1 adducts are formed. There exists implicit evidence for the hydrolytic dissociation of the neutral LnL3 complexes in benzene solution.
