Improving the Stability and Kinetic Inertness of Mn(II) Complexes by Increasing the Bridge Length in Bicyclic CDTA‐Like Ligands

“…reveals that the Zn(II) ion is hexacoordinated by two nitrogen and two carboxylate oxygen donor atoms in a square planar fashion and with other two carboxylate donors in axial positions which complete the coordination sphere in a distorted octahedral geometry. [42] The X-ray structure of [Zn-…”

Synthesis, crystal structure and luminescence of three europium complexes with 2-iodobenzoic acid

“…We reported four terbium 2-fluorobenzoic acid complexes [Tb(2-FBA) 3 3 Á phen Á CH 3 CH 2 OH] 2 þ [Tb(2-FBA) 3 Á phen] 2 } (2-HFBA: 2-fluorobenzoic acid, 4,4 0 -bpy: 4,4 0 -bipyridine, 2,2 0 -bpy: 2,2 0 -bipyridine, phen: 1,10-phenanthroline) [5]. As part of our investigation of lanthanide carboxylate complexes, we synthesized three new europium 2-iodobenzoic acid complexes, (2), and [Eu(2-IBA) 3 Á phen] 2 (3) (2-IBA ¼ 2-iodobenzoate). The crystal structure 1 shows an infinite polymeric chain due to carboxylate groups in a bridgingchelating-bridging coordination mode.…”

“…Many lanthanide carboxylate complexes have been reported, such as binary carboxylate complexes [1][2][3][4][5][6][7], ternary and quaternary carboxylate mixed-ligand complexes containing 4,4 0 -bipyridine(4,4 0 -bpy), 2,2 0 -bipyridine (2,2 0 -bpy), and 1,10-phenanthroline(phen) [4,5,[8][9][10][11][12][13][14], exhibiting diverse structural types. A large number of lanthanide carboxylate complexes have been found to be polymeric or dimeric due to variation of the coordination modes of the carboxylate group.…”

“…Molecular structure of complex(2). All hydrogen atoms have been omitted for clarity; the thermal ellipsoids are shown at the 30% probability level.1522X.Li et al an exothermic peak at 479.0 C, correspond to total mass loss of 81.06%, indicating the complex is completely degraded into Eu 2 O 3 (theoretical mass loss 80.68%).…”
