【 摘 要 】

The synthesis and structural characterization of five transition metal complexes with different dimensionality and incorporating residues of 3-amino-1H-1,2,4-triazole-5-carboxylic acid (H₂atrc) is reported: [Zn(Hatrc)₂(H₂O)] (1), [Mn(Hatrc)₂(H₂O)₂]·2H₂O (2), [Fe₂(Hatrc)₄(OH)₂]·6H₂O (3), [Cd(Hatrc)₂(H₂O)]_n (4), and [Mn(atrc)(H₂O)]_n·nH₂O (5). These materials could be prepared from solution (1–3), diffusion (4), or hydrothermal reactions (5) with various anions and L:M ratios. Structural details were revealed by single crystal X-ray diffraction. The discrete units composing compounds 1–3, the polymeric 1D chain of 4 and the 2D layer of 5 are further extended into 3D supramolecular architectures through the formation of hydrogen bonds.
