“…An interesting property of isonicotinic acid is its ability to form three-dimensional polymeric structures with transition metal ions and lanthanides, binding by the nitrogen atom from the pyridine ring, and by the carboxylic group oxygens [3][4][5]. Some isonicotinic coordination compounds obtained by different synthetic routes and with different structures are well known [6][7][8][9][10][11]. Some of them presents biological properties, as in preventing intravenous thrombosis [neodymium(III) and samarium(III) isonicotinate].…”

Characterization, thermal stability, and thermal decomposition of light trivalent lanthanide isonicotinates Ln(L) 3 Á2H 2 O (Ln = La to Gd, except Pm; L = isonicotinate) were investigated employing simultaneous thermogravimetry and differential scanning calorimetry (TG-DSC), DSC, infrared spectroscopy (FTIR), evolved gas analysis by TG-DSC coupled to FTIR, elemental analysis, and complexometry. The dehydration of these compounds occurs in a single step, and the thermal decomposition of the anhydrous compounds occurs in one or two (air) and two or three steps (N 2). The final residues of thermal decomposition were CeO 2 , Pr 6 O 11 , and Ln 2 O 3 (Ln = La, Nd to Gd) in air atmosphere, while in N 2 atmosphere the mass loss is still being observed up to 1000°C. The results also provided information concerning the gaseous products evolved during the thermal decomposition in dynamic dry air and nitrogen atmospheres.

Europium(III) and terbium(III) complexes have been prepared using the ligands 2‐(4,5‐dihydro‐1,3‐oxazol‐2‐yl)phenol (HL1) and 2‐(4,5‐dihydro‐1,3‐thiazol‐2‐yl)phenol (HL2) in yields ranging between 74 and 100 %. Metal‐to‐ligand ratios of 1:3 and 1:4 can be achieved, giving rise to compounds with the formulae [Ln2(L)6] and NR4[Ln(L)4], Ln = Eu, Tb. Recrystallisation of the complexes from DMSO resulted in the formation of octanuclear complexes [Na2(Ln(L1)3)2(CO3)(DMSO)2]2 held tightly together by carbonate ions that have been formed from CO2 from the atmosphere. Five structures have been determined, showing a bidentate binding mode of the ligand through the phenolate oxygen and the nitrogen atom of the five‐membered ring. Most terbium compounds show bright luminescence upon excitation with near‐UV radiation, with quantum yields of 16 % to 79 %. Strong emission is observed for NBu4[Eu(L1)4] and NEt4[Eu(L2)4] with quantum yields of 43 % and 20 %, respectively.

Reaction of hydrated lanthanum halides (Ln=La, Pr and Nd) with LH2 [1‐(2‐HydroxyPhenyl)‐3‐(2‐thienyl)‐1,3‐Propanedione] in presence of excess triethylamine with methanol as a solvent resulted in the isolation and structural characterization of a series of novel hexanuclear lanthanide clusters templated by µ6‐CO32− introduced via spontaneous fixation of atmospheric carbon dioxide depicting a new coordination mode of binding. This particular mode of bridging is a first report of its kind in lanthanide clusters. Magnetic analysis of the praseodymium and neodymium analogue shows strong antiferromagnetic interactions in case of praseodymium and weak antiferromagnetic interactions in case of neodymium.
