So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Singh, Vikram; Liu, Shuang; Ma, Pengtao; Drew, Michael G. B.; Wang, Jingping; Niu, Jingyang researched the compound: 6-Methylnicotinic acid( cas:3222-47-7 ).Reference of 6-Methylnicotinic acid.They published the article 《Versatile {Cp2Ti} Grafted Hetero-Polyoxotungstate Clusters: Synthesis, Crystal Structure, and Photocurrent Properties》 about this compound( cas:3222-47-7 ) in Inorganic Chemistry. Keywords: titanocene grafted phosphotungstate cluster preparation crystal mol structure photocurrent; crystal mol structure titanocene grafted phosphotungstate cluster. We’ll tell you more about this compound (cas:3222-47-7).
Polyoxotungstate supported titanocene {Cp2Ti}2+ clusters H6{K8(Cp2Ti)2P4W24O88(PO4)2}·14H2O (1), H6[Na2P4W14O58(Cp2Ti)2]·12H2O (2), and H2[K6{Cp2Ti}{PW9O33(WO2)}2{NC5H3(COOK)2}(NC5H3(CH3)COOK)·22H2O] (3) have been synthesized, and their single crystal x-ray structures have revealed unprecedented and intriguing structural features. The synthesized compounds have been characterized by various spectroscopic techniques including UV-vis, cyclic voltammogram, NMR, ESI-MS, and inductive coupled plasma spectroscopy (ICP) in solution and also by IR, TGA, and diffuse reflectance in the solid state. Clusters 1 and 2 are rare examples of lacunary POM supported titanocene clusters obtained by incorporating various phosphorus heteroatoms to form elusive phosphotungstate assemblies, whereas 3 is an unprecedented organometallic as well as heteroleptic pyridyl functionalized POM. Clusters 1-3 show transient photocurrent ON/OFF behavior upon UV-light irradiation and also exhibit characteristic TiIV/III intravalence electron transfer. This behavior is also established by their cyclic voltammograms in mixed phosphate buffers (Na2HPO4/NaH2PO4) which show the evidence of POM supported {Cp2Ti}2+/+ species in their redox solution Furthermore, ESR line broadening is also observed in these clusters at room temperature, a fact which also confirms the formation of partially reduced/oxidized {Cp2Ti}2+/+ species leading to TiIV/III intravalence electron transfers within all three clusters. The {Cp2Ti}2+ decorated polyoxometalate cluster 3 shows improved transient photocurrent behavior which may be due to the presence of pyridyl carboxyl ions which provide better surface contact for the cluster mol. through the carboxylate moiety to the ITO electrode.
