文摘

The optical and magnetic properties of K₂PrCl₅ were investigated in the 1.7–293 K temperature range and are discussed on the basis of the X-ray crystal structure data. High-resolution absorption, emission, and excitation spectra as well as decay time measurements at 293, 77, and 4 K are presented and used to characterize the excited state photophysics of K₂PrCl₅. Magnetic susceptibility measurements were carried out down to 1.7 K in both the low and high field regime. Changes in the magnetic moment with temperature are discussed on the basis of the structural data. Spectroscopy and magnetism of K₂PrCl₅ are related to respective results of other polynuclear and heteronuclear polymeric systems and are correlated with their EPR data.
