Charge transfer complexes of lanthanide 3,5-dinitrobenzoates and 1,2-phenylenediamine

Biological Activity of Complexes Involving Nitro-Containing Ligands and Crystallographic-Theoretical Description of 3,5-DNB Complexes

“…In this context, several binuclear lanthanides 3,5-dinitrobenzoates with N,N-dimethylaniline (DMA) [ 103 ], 1,2-phenylenediamine [ 57 ], and N,N,N′,N′-tetramethyl-p-phenylenediamine were synthesized by Koroteev et al [ 104 ], which showed interesting charge transfer properties that give rise to magnetism according to the amount of charge transfer, where Dysprosium complexes even show a single-molecule magnetic behavior. Moreover, coordination polymers based on bridged dicyanamido-metal(II) building units were synthesized, with their structural and magnetic characteristics rationalized via DFT calculations, by Mautner et al [ 105 ].…”

Synthesis, crystal structure and Hirshfeld surface analysis of diaquabis(o-phenylenediamine-κ2 N,N′)nickel(II) naphthalene-1,5-disulfonate

“…OPD is also a versatile ligand in coordination chemistry. It forms complexes with different metal ions, such as lanthanides (Koroteev et al, 2020), zinc (Gonza ´lez Guillen et al, 2018;Zick & Geiger, 2016), cobalt (Ngopoh et al, 2015;Konieczny et al, 2019), copper (Djebli et al, 2012;Chakraborty et al, 2014), cadmium (Gonza ´lez Guillen et al, 2018) or nickel (Sabbani & Das, 2009;Lu et al, 2009;Willett et al, 2012;Adhikari et al, 2021).…”

Improving thermal‐oxidative stability of nitrile butadiene rubber composites by surface modification of zirconium phosphate

“…O-Phenylenediamine (OPD), known as 1,2-phenylenediamine, is often used as an intermediate in the preparation of photographic materials, pharmaceuticals, dyes and rubber antioxidants due to its good radical-capturing activity. [14][15][16][17][18] It has been reported that the chemical grafting of OPD onto graphene oxide, the hydroxyl group of graphene oxide can react with the amino group of OPD to generate new quinone and phenazine structures, which improve the mechanical properties and aging resistance of NBR composite. [19] However, graphene oxide is costly and not conducive to widespread applications.…”
