Synthesis, crystal structure and magnetic properties of new copper(II) complexes based on 3-(2-pyridyl)-1,2,4-triazole

An investigation of two copper(ii) complexes with a triazole derivative as a ligand: magnetic and catalytic properties

“…It is worth mentioning that the obtained constants are higher than for the analogous ligand described earlier, which results from the electron donating effect of the methyl substituent on the triazole ring. 30 …”

Complex formation in solution upon mixing HL ligand with copper(II) ions was rst monitored using ESI-MS.…”

Crystal structure and Hirshfeld-surface analysis of diaquabis(5-methyl-1H-1,2,4-triazole-3-carboxylato)copper(II)

“…The presence of three nitrogen atoms and the possibility of being involved in metal bonding, both in their acid and deprotonated forms, resulted in the synthesis and investigation of numerous coordination compounds based on 1,2,4-triazole derivatives (Haasnoot, 2000). As a result of the presence of the N-N bridging function in the triazole ring, these ligands can form polynuclear complexes with specific magnetic properties (Aromı ´et al, 2011;Kitchen & Brooker, 2008;Klingele & Brooker, 2003;Petrenko et al, 2020;. Meanwhile, 1,2,4triazole used as linker in ligands for MOF construction, is not usually involved in the formation of coordination bonds (Du et al, 2005).…”

Synthesis and crystal structure of hydrated μ-oxalato-bis{bis[3-methyl-5-(pyridin-2-yl)-1H-1,2,4-triazole]iron(II)} bis(toluenesulfonate) 2.75-hydrate

“…The study of coordination compounds based on substituted 1,2,4-triazoles and 3d and 4d transition metals allows the design of supramolecular structures that can find applications in various fields such as molecular magnetism, catalysis, electrochemistry or cluster engineering (Zhang et al, 2017;Zakharchenko et al, 2019;Chen et al, 2015;Petrenko et al, 2020Petrenko et al, , 2021. The presence of the pyridine ring in such triazole systems leads to the formation of interesting isolated metalorganic frameworks that demonstrate promising magnetic properties, making them suitable for application as moleculebased magnets (Yao et al, 2015;Han et al, 2017;Li et al, 2015;Huang et al, 2015).…”
