Influence of the nature of the substituent in 3-(2-pyridyl)-1,2,4-triazole for complexation with Pd2+

Solvent- and functional-group-assisted tautomerism of 3-alkyl substituted 5-(2-pyridyl)-1,2,4-triazoles in DMSO–water

“…The synthesis of compounds 9a–b , 67 9c–e , 1 d and 9g 1 d have been performed following procedures described in the literature. All the starting materials were obtained from Enamine Ltd. and UORSY (UkrOrgSyntez Ltd).…”

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

“…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). The most widely used ligands of such type are 3-(2-pyridyl)-1,2,4-triazole derivatives, which readily form extremely stable planar coordination compounds with platinum (Chang et al, 2006;Chen et al, 2013) and palladium (Zakharchenko et al, 2017;, showing promising photoelectronic and catalytic properties, respectively. A carboxylic acid group connected directly to the 1,2,4-triazole ring could potentially play the same role as a 2-pyridyl moiety, forcing the formation of chelates.…”

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

“…A few examples with a similar type of ligand indicate that complexes of this kind possess interesting magnetic and oxidizing properties (de Ruiter et al, 2008;Oliveira et al, 2018). In order to continue research in this field and in the course of our studies dedicated to the investigation of triazoles and, in particular, 3-methyl-5-(pyrid-2-yl)-2H-1,2,4-triazole (metrzpy) (Zakharchenko et al, 2017;Zakharchenko, Khomenko, Doroschuk, Raspertova, Fesych et al, 2021;Zakharchenko, Khomenko, Doroshchuk, Raspertova, Shova et al, 2021), we report herein the synthesis and crystal structure of a new binuclear iron(II) complex with this ligand.…”

“…The triazole ligand was prepared according to a synthesis described in the literature (Zakharchenko et al, 2017). Single crystals of [Fe 2 (C 2 O 4 )(metrzpy) 4 ](CH 3 C 6 H 4 SO 3 ) 2 Á2.75H 2 O were obtained by the liquid-to-liquid diffusion technique using a layering tube.…”
