A series of novel metal-ferrocenedicarboxylate coordination polymers: crystal structures, magnetic and luminescence properties

Investigation of Molecular Interactions in the Carboxylato Zn(II) and Cd(II) Macrocyclic Complexes

“…[16][17][18][19] An fdc (fdc = 1,1'-ferrocenedicarboxylate ion) ligand as a kind of polycarboxylates has attracted attention not only in the field of coordination chemistry but also in the field of organometallic chemistry. [20][21][22][23] During our efforts to explore the molecular interactions between metallomacrocycles and polycarboxylate ligands in zinc(II) and cadmium(II) tetraazamacrocycles containing bridging polycarboxylate ligands, we successfully synthesized and structurally characterized two 1D zinc(II) coordination polymers 1 and 2, where each ferrocenyl of bridging fdc ligands adopts different conformation, and a macrocyclic cadmium(II) dimer 3. Thus, two Cp (Cp = cyclopentadienyl) rings of fdc ligands in 1 are mutually staggered, whereas they are eclipsed in 2.…”

Tetrametallic macrocyclic frameworks constructed from ferrocenedicarboxylato and 2,2′-bipyridine: synthesis, molecular structures and characteristics

“…In this context, ferrocenedicarboxylic acid or its sodium salt as a very important carboxylate derivative has attracted much attention. It has been exploited as a multifunctional ligand due to the size and the strong inductive effect of ferrocene and the versatile coordination modes of carboxylate anions [16][17][18][19][20][21][22][23][24][25][26][27]. Scheme 1 illustrates the reported coordination modes of ferrocenedicarboxylate anions.…”

“…In our previous paper, similar photoluminescences have been reported for the two-dimensional layered polymers {[Á mH 2 O} n (Fc ¼ (g 5 -C 5 H 4 )Fe(g 5 -C 5 H 4 ), M ¼ Tb 3þ , Eu 3þ , Y 3þ ; m ¼ 1 or 2) and one-dimensional wave-shaped polymer {[Cd(g 2 -O 2 CFcCO 2 -g 2 )(H 2 O) 3 ] Á 4H 2 O} n with maximum emission at 393 nm[26].…”

A nano-scale double-wheel-like framework: A novel assembly of six ferrocenedicarboxylate units with unusual coordination modes

“…In the reported complexes, the ferrocenedicarboxylate moieties usually exist as bi-(OOCFcCOO) coordination mode such as in complexes [Cu 2 {Fc(COOH) 2 } 2 (py) 2 -(DMF) 2 (H 2 O) 2 ], [Zn{Fc(COOH) 2 }(1-methylimidazole) 2 ] 2 , and [M 2 (O 2 CFcCO 2 ) 2 (2,2 0 -bpy) 2 (l 2 -OH 2 ) 2 ] (M = Co, Ni) [3e,3f], tri-(g 2 -OOCFcCOO) mode such as in complexes Ni 2 {Fc(COOH) 2 } 2 (py) 4 (H 2 O) and [M 2 (g 2 -O 2 CFcCO 2 ) 2 (2,2 0 -bpy) 2 (H 2 O) 2 ] (M = Zn, Cd) [3b,3f], tetra-(g 2 -OOCFc COO-g 2 ) mode such as in complex {[Cd(O 2 CFcCO 2 )(H 2 O) 3 ] AE 4H 2 O} n [8]. In complexes {[M(O 2 CFcCO 2 ) 1.5 (H 2 O) 2 ] AE mH 2 O} n (M = Tb 3+ , or Eu 3+ , or Y 3+ ; m = 1 or 2), ferrocenedicarboxylate groups coordinate to metal ions as tetra-(g 2 -OOCFcCOO-g 2 ) and hexa-(l 2 -g 2 -OOCFcCOOg 2 -l 2 ) modes simultaneously [8].…”

“…In complexes {[M(O 2 CFcCO 2 ) 1.5 (H 2 O) 2 ] AE mH 2 O} n (M = Tb 3+ , or Eu 3+ , or Y 3+ ; m = 1 or 2), ferrocenedicarboxylate groups coordinate to metal ions as tetra-(g 2 -OOCFcCOO-g 2 ) and hexa-(l 2 -g 2 -OOCFcCOOg 2 -l 2 ) modes simultaneously [8]. To the best of our knowledge, ferrocenedicarboxylate groups coordinating to metal ions as hexa-(l 3 -À OOCFcCOO À -g 2 -l 2 ), hexa-(l 2 -g 2 -À OOCFc2COO À -g 2 -l 2 ) and hepta-(l 2 -g 2 -À OOCFc3COO À -g 2 -l 3 ) modes at the same time are not reported, and the coordination modes of hexa-l 3 -À OOCFc1COO À -g 2 -l 2 and hepta-l 2 -g 2 -À OOCFc3COO À -g 2 -l 3 are unprecedented.…”
