Abstract 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: ZnHatrc2H2O 1, MnHatrc2H2O2·2H2O 2, Fe2Hatrc4OH2·6H2O 3, CdHatrc2H2On 4, and MnatrcH2On·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.
