Thermal investigation and infrared evolved gas analysis of light lanthanide(III) complexes with pyridine-3,5-dicarboxylic acid

Synthesis, evolved gas analysis (EGA) during pyrolysis and spectroscopic study of light lanthanide nicotinate in solid state

“…Because of this, many studies have been conducted regarding metal lanthanides and their derivatives [1][2][3][4][5][6]. Many of these derivatives are created from the coordination of lanthanides with organic and biological molecules such as nicotinic acid (3-picoline, vitamin B3 or pyridine-3-carboxylic acid), which is the biological precursor of the co-enzymes, nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP).…”

Microwave-assisted synthesis of lanthanide 2,6-naphthalenedicarboxylates: Thermal, luminescent and sorption characterization

“…The peak-top temperatures of only the strongest effects are given in Table 1. In the case of the cerium complex, removal of DMF molecules does not result in formation of stable Ce 2 ndc 3 but leads to direct decomposition to CeO 2 similarly to that observed for other cerium polycarboxylates [35,59,60]. For the remaining compounds, the desolvation process leads to the formation of Ln 2 ndc 3 compounds stable in the temperature range (275-445°C) as can be seen in Table 1.…”

“…For the remaining compounds, the desolvation process leads to the formation of Ln 2 ndc 3 compounds stable in the temperature range (275-445°C) as can be seen in Table 1. The next distinct weight losses observed on the TG curves (air) are connected with decomposition of Ln 2 ndc 3 and burning organic ligand to the appropriate oxides (Ln 2 O 3 , Pr 6 O 11 and Tb 4 O 7 ) [59][60][61].…”

Some properties of Nd and Er complexes with 1,2,3,4,5,6-benzenehexacarboxylic (mellitic) acid

“…The scheme of behavior (air) of the inves- tigated complexes is as follows: hydrated complex → anhydrous complex → oxide. This pathway of thermal behavior is very characteristic of the lanthanide organic complexes and it was reported in many papers [32][33][34].…”
