Synthesis, crystal structure and properties of novel isostructural two-dimensional lanthanide-based coordination polymers with 2,3,5,6-tetrafluoro-1,4-benzenedicarboxylic acid

A Porous 4d–4f Heterometallic Coordination Polymer: Synthesis, Crystal Structure and Physical Properties

“…Each La III ion is coordinated by nine oxygen atoms from six pydc 2– ligands in a distorted monocapped square antiprism geometry. The distances of La–O bonds range from 2.460(7) to 2.693(8) Å, similar to those in other La III carboxylate complexes 37–39. The O–La–O bond angles range from 49.3(3) to 148.3(2)°.…”

Synthesis of Octafluorobiphenyl-4,4′-dicarboxylic acid and photoluminescent compounds based thereon

“…The strongest emission band was the "red" one at λ mах = 614 nm. The bands positions were close to those in the Eu 2 (L') 3 (DEF) 2 (EtOH) 2 ·2(DEF) photoluminescence spectrum (DEF = diethylformamide): λ mах = 590, 615, 650, and 695 nm [13].…”

Crystal structure of poly-[tetraaqua-bis(μ4-2,5-dibenzoyl-1,4-benzenedicarboxylato-κ4 O 1:O 2:O 3:O 4)-μ2-2,5-dibenzoyl-1,4-benzenedicarboxylato-k4 O 5,O 6: O 5′,O

“…Lots of works have been concentrated on designing and synthesizing lanthanide-MOFs on aromatic ligands [2]. The bridging carboxylate ligands, such as 1,3/1,4-benzenedicarboxylate [3,4] as well as modi ed 1,3/1,4-benzenedicarboxylate [5,6], have frequently being utilized to produce polymeric structures. In addition, the structural sophistication can be further enhanced through the use of ancillary co-ligands.…”
