| Abstract: | The desolvation process in lanthanide pyridine-3,5-dicarboxylates of the formulae Tb2pdc3(dmf)2]·dmf (1), Ho2pdc3(dmf)2]·dmf (2), Erdc3(dmf)2]·dmf (3), and Yb2pdc3(dmf)2]·dmf (4) where pdc-C5H3N(COO)22−, dmf-N,N′-dimethylformamide) has been investigated by means of the TG–DSC, TG–FTIR, IR and XRD methods. Heating of the complexes in
the range 30–260 °C lead to evolution of weakly bonded dmf molecules included in the channels as well those directly bonded
with lanthanide atoms. The kinetic analysis revealed a multistep desolvation pattern. |
