Synthesis, structure and property of two d-f heteronuclear Eu-TM (TM = Zn and Cd) complexes with open-chain ether Schiff base 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

“…These ligands are largely used for the synthesis of complexes with biochemical and physical properties [10][11][12][13]. 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].…”

A one‐dimensionalCd‐Eucoordination polymer with open‐chain ether Schiff base ligand and 4,4′‐bipyridine: Synthesis, structure, luminescence property, and antioxidation activities

“…The activities of ligand and the Cd‐Eu CP in scavenging hydroxyl radicals are shown in Figure 5a, and both display significant inhibition of OH. Table 4 summarizes the following data of hydroxyl radical scavenging activity (IC 50 ): ligand and the Cd‐Eu CP; single lanthanide complexes or d–f clusters or d–f CPs based on open‐chain ether Schiff base ligands; [ 39,41,43,46 ] natural antioxidants such as mannitol [ 67 ] and vitamin C. [ 68,69 ] Comparing the data, the scavenging ability of ligand and CP on hydroxyl radicals is more excellent than that of mannitol and vitamin C, and slightly better than part of other structures in the table.…”

“…In previous studies, a series of single transition metals complexes, single lanthanide metals complexes, and d–f clusters with open‐chain ether Schiff base have been reported by our group, [ 38–47 ] yet the research of bridging ligands based d–f CPs is scant. Herein, Cd(II) and Eu(III) have been introduced and coordinated with H 2 L, then the bridged ligand 4,4′‐bipyridine was introduced to form the one‐dimensional d–f CP successfully, and its luminescence and biological properties were further expatiated.…”

Magnetic properties of a europium(iii) complex – possible multiplet crossover

“…12 Eu(III) is widely used to prepare heterometallic (4f-3d type) or homometallic (4f-4f type) complexes. [13][14][15][16][17][18][19][20][21][22][23][24][25][26] Generally, the combination of anisotropic or isotropic metals of lanthanides with first row 3d metals in a suitable chelate pocket (e.g., Schiff base) gives a strong premise for the discovery of slow magnetic relaxation or valuable luminescence properties. [13][14][15][16][17][18][19][20][21][22][23][24][25][26] The next field of inter-est is to explore the magnetic properties of organic radicalbased Eu(III) structures.…”

[27][28][29] The dinuclear complex [(H 2 O)Cu II (LH)Eu III (NO 3 ) 3 ] (hereafter referred to as A) containing the Eu(III) centre was previously studied by DC magnetometry and AC susceptometry.…”
