The reactions of Pr2O3 and Pr6O11 with Cl2(g) were studied thermodynamically and experimentally, and proposed in the systems Pr2O3/Cl2(g) and Pr6O11/Cl2(g). A kinetic analysis was performed on Pr6O11 chlorination, which differs from with other light rare earth oxide chlorinations. The praseodymium oxychlorides obtained by full chlorination of Pr6O11 at 425 °C and 800 °C are different, being well characterized by X-ray diffraction, scanning electron microscopy, magnetic susceptibility measurements and X-ray photoelectron spectroscopy. The crystal structures of the oxychlorides were refined with the Rietveld method. The comparison between the theoretical magnetic moment of Pr3+ and the estimated magnetic moment in the praseodymium oxychloride obtained at 425 °C revealed the presence of Pr3+ and Pr4+, whereas no significant difference was observed between the theoretical and the experimental values of Pr3+ obtained for the praseodymium oxychloride prepared at 800 °C. These observations are consistent with the analyses in the X-ray photoelectron spectra for both oxychlorides. Finally, a general formula of PrO1+xCl is proposed for the oxychlorides synthesized at T 800 °C.

Carboxylato-bridged 3D polymeric networks of Pr(III): Synthesis, crystal structure, magnetic property and thermal behavior

, p. 160 - 164 (2010)
A novel polymeric carboxylato-bridged praseodymium(III) complex of fumarate, [Pr2(fum)3(H2O)4] ·5H2O (fum, fumarate dianion) has been synthesized and characterized by single-crystal X-ray diffraction studies, magnetic measurements and thermal studies. Single crystal X-ray structural determination reveals that it is a new porous three dimensional pillared layer framework with 1D channel for the accommodation of tetrameric water clusters. A preliminary treatment of the variable-temperature magnetic susceptibility using an expression including the ligand field effects and molecular field approximation leads to zJ′ = -1.60 cm-1, Δ = 0.5 cm-1 and g = 0.84, suggesting the existence of a weak antiferromagnetic coupling between the praseodymium ions.
