Abstract

•Two new copper(II) complexes were synthesized and structurally characterized.•The magnetic analysis was carried out according to their different structures.•Different bridges play the dominate role in the magnetic properties.

By utilizing 4-amino-3,5-dimethyl-1,2,4-triazole as ligand, two new compounds, [Cu3(N3)6(L)4] (1) and {[Cu3(NO3)5(OH)(L)3]·0.5H2O}n (2) (L = 4-amino-3,5-dimethyl-1,2,4-triazole), have been synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, UV–Vis spectra and magnetic measurements. Compound 1 is a trinuclear Cu(II) complex, containing four L ligands and six N3− anions. In compound 2, a one-dimensional chain structure was formed between the trinuclear Cu(II) units connected to each other by NO3− anions. The magnetic analysis indicates a middle strong antiferromagnetic exchange is propagated by 1,2,4-triazole bridging ligand.

Graphical abstractTwo new triazole-bridged complexes, [Cu3(N3)6(L)4] (1) and {[Cu3(NO3)5(OH)(L)3]·0.5H2O}n (2) (L = 4-amino-3,5-dimethanyl-1,2,4-triazole), have been synthesized and structurally characterized. Compound 1 is a trinuclear Cu(II) complex and compound 2 has a one-dimensional chain structure. The magnetic analysis indicates intramolecular antiferromagnetic coupling between Cu(II) ions is propagated.Figure optionsDownload full-size imageDownload as PowerPoint slide
