Abstract

The new 1D coordination polymer {Tm(Piv)3}n (1), where Piv=OOCBut−, was synthesized in high yield (>95%) by the reaction of thulium acetate with pivalic acid in air at 100°С. According to the X-ray diffraction data, the metal atoms in compound 1 are in an octahedral ligand environment unusual for lanthanides. The magnetic and luminescence properties of polymer 1, it’s the solid-phase thermal decomposition in air and under argon, and the thermal behavior in the temperature range of −50…+50°С were investigated. The vaporization process of complex 1 was studied by the Knudsen effusion method combined with mass-spectrometric analysis of the gas-phase composition in the temperature range of 570–680K.
