The N-(2-carboxyphenyl)salicylideneimine ligand in 4f-metal chemistry: A unique neodymium(III) chain containing the singly deprotonated, zwitterionic form of the ligand

Synthesis, Characterization and Single Crystal X–ray Crystallography of Nd(III) and Pr(III) Complexes with the Tridentate Schiff Base Ligand N'–(1–(pyridin–2–yl)ethylidene)nicotinohydrazide

“…The formation of acyclic ligand complexes depends on the flexibility of the coordinating groups [14][15][16], the nature of the donor atoms [17][18][19] and the complexing properties of the ions acting as counter-anions [20][21][22]. The use of Schiff bases in coordination chemistry has made it possible to develop molecular materials with specific properties [23][24][25]. This article describes the tridentate Schiff base obtained by the reaction between nicotinohydrazide and acetylpyridine.…”

Photophysical properties and computational study of newly synthesized lanthanide complexes with N-(2-carboxyphenyl)salicylideneimine Schiff base ligand

“…Hydrated lanthanide salts (Ln(NO 3 ) 3 A are the absorbances of the DPPH radical in the presence and absence of sample (antioxidant), respectively. The experiment was repeated three times.…”

“…Ni} [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. A variety of coordination modes were proposed depending on reaction conditions, nature of the metal and stability of the complex formed [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. The coordination behavior of LH 2 ligand towards Ln(III) ions will be investigated via elemental analysis, spectroscopic analysis (UV-Visible, FTIR, 1 H and 13 C NMR), molar conductance and thermal analysis.…”

Multifunctionality in Two Families of Dinuclear Lanthanide(III) Complexes with a Tridentate Schiff-Base Ligand

“…Our efforts have led to two families of complexes depending on the metal ion used; preliminary studies on representative members of the families reveal a triple functionality concerning slow magnetic relaxation, light emission, and homogeneous catalysis. The Schiff base LH 2 is a rather well-known ligand in 3d metal chemistry; , however, its use in 4f metal chemistry is negligible. , …”

“…The Schiff base LH 2 is a rather well-known ligand in 3d metal chemistry; 21,22 however, its use in 4f metal chemistry is negligible. 23,24 The reactions of Ln(NO 3 ) 3 •xH 2 O (x = 5 or 6) and LH 2 25 in 1:2 molar ratios in methanol (MeOH)−acetonitrile (MeCN) The crystal structure of the representative complex 2•MeOH contains two crystallographically independent, centrosymmetric [Gd 2 (NO 3 ) 4 (LH) 2 (MeOH) 4 ] molecules (Figures 1 and S1 and Table S1). The two Gd III atoms are bridged by the syn,syncarboxylate groups of two η 1 :η 1 η 1 μ 2 (or 2.111 using Harris notation; Scheme S1b) LH − ligands.…”
