A 1D zinc(II) polymer with W-like pentanuclear secondary building blocks constructed by 2,6-pyridine-diacylhydrazone ligand

Abstract

A 1D zinc(II) coordination polymer with W-like pentanuclear secondary building blocks constructed by 2,6-bis[(3-methoxysalicylidene)hydrazinocarbonyl]pyridine (H 4 Bmshp) ligand, {[Zn 5 (Bmshp)(CH 3 COO) 5 Cl(H 2 O) 3 ]Á 2H 2 O} n , was synthesized and characterized by elemental analysis, IR, X-ray diffraction, and thermogravimetric analyses. It has the highest nuclear unit constructed by one 2,6-pyridine-diacylhydrazone ligand so far. The luminescent property of the compound was studied. It shows an emission with a maximum at 522 nm upon excitation at 450 nm.

Heteroleptic (2-Fluoro-3-pyridyl)arylborinic 8-Oxyquinolinates for the Potential Application in Organic Light-Emitting Devices

“…Currently, the chemistry of zinc pyridine complexes is rapidly expanding. − Recently, Jäkle and co-workers reported that complexation of a borinic polymeric system bearing attached pyridine moieties with zinc tetraphenylporphyrin changed the wavelength of emission . This has prompted us to investigate the formation of complexes between our compounds and ZnCl 2 .…”

“…The experimental study by Qin et al [152] reports the synthesis and characterization, including single crystal X-ray analysis of {[Zn 5 (Bmshp)(CH 3 COO) 5 Cl(H 2 O) 3 ]Á 2H2O} n ; H 4 Bmshp ligand = 2,6-bis[(3-methoxysalicylidene)hydrazinocarbonyl]pyridine. The pentanuclear unit, as determined for this compound, is currently the highestnuclearity unit known constructed on one 2,6-pyridinediacylhydrazone ligand.…”

Synthesis, density functional theory calculations and luminescence of lanthanide complexes with 2,6‐bis[(3‐methoxybenzylidene)hydrazinocarbonyl] pyridine Schiff base ligand

“…In the recent past, pyridine‐diacylhydrazones ligands possessing a central pyridine ring and two alkoxybenzaldehyde moieties on each side connected by a carbohydrazide linkage have attracted much attention not only for their aesthetically fascinating structures but also for their broad range of biological activities such as antioxidant, antimicrobial, anticancer, antiinflammatory, analgesic, hypotensive, agonistic, and hallucinogenic . Furthermore, pyridine‐diacylhydrazones are important multidentate ligands for the construction of coordination complexes with metal centers . Their metal complexes have attracted intense interest in many areas such as multimetallic enzymes, homogeneous and heterogeneous catalysis …”
