Abstract

The hydrothermal reactions of K₃[M(C₂O ₄)₃] (M=Co, Fe) and imidazole (im) molecule result in the syntheses of two oxalate-bridged transition-metal supramolecular polymers: [Co(im)₂(C₂O₄)] 1 and [Fe₂(im) ₄(C₂O₄)₂] 2. Both exhibit the one-dimensional (1D) zigzag chain structures with the tetradentate oxalato bridges and ancillary im molecules, and are further propagated into a 3D supramolecular network via the interchain weak N-H⋯O hydrogen bonds. The TG behaviors of both are studied and thermally stable up to ca. 180 and 270°, respectively. The third-order non-linear optical properties of both were also studied, and both exhibit the reverse saturable absorption and self-defocusing performance with the γ values of 1.55×10 ^-31 esu for 1 and 1.02×10^-31 esu for 2, respectively.
