| Abstract: | A novel boat-shaped praseodymium (III)-carboxylate polymeric complex Pr(Hbtec)]n (H4btec = 1,2,4,5-benzenetetracarboxylic acid) with 3-D interlinked structure, which contains nine-coordinate rare earth metal centers, simplified as PRCPC, has been synthesized under hydrothermal conditions. The frames interlinked with each other and formed a unique boat-like alignment. PRCPC that was obtained was characterized by differential thermal analysis/thermogravimetry (DTA/TG), single crystal X-ray diffraction, elemental analysis and FTIR spectral analysis. Analysis of the single-crystal X-ray diffraction confirms that PRCPC crystallizes in triclinic symmetry with space group (P ? 1), where a = 7.325(3), b = 8.162(3), c = 8.791(3) Å, α = 65.345(4), β = 86.015(4), γ = 84.203(5)°, V = 475.0(3) Å3, Z = 2, R1 = 0.0201, wR2 = 0.0505. PRCPC exhibits high thermal stability and its supramolecular frame remains stable without any change under heat treatment to 510°C. |
