A study on the structure and magnetic properties of |Pr(NO 3)(Pic)(H2O)2(EO3)](Pic) complex, where EO3 - triethylene glycol and Pic-picrate anion was conducted and characterized by single crystal X-ray structure analysis. Magnetic susceptibility χ/M) was carried out from 2 to 300 K under both field-cooled (FC) and zero-field-cooled (ZFC) measurements with an applied magnetic field of 2000 Oe. The complex is crystallized in triclinic with space group Pi. The coordination geometry around the Pr(IIl) ion was a tetradecahedron with a ten-coordination number. In the crystal, the molecular structure was stabilized by moderate and weak hydrogen bonding interactions between the cation [Pr(NO3) (Pic)(H 2O)2(EO3)]+ moiety and [Pic] as counter-anion that led to the formation of a one-dimensional network. The temperature dependence of the magnetic susceptibility of [Pr(NO 3)(Pic)(H2O)2(EO3)](Pic) shows the presence of weak antiferromagnetic interactions between the Pr(III) centers. The magnetic susceptibility for complex also obeys the Curie-Weiss law and is effective at high temperatures. Some factors that influence the photoluminescence intensity were also reported.
