Application of 499-40-1, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 499-40-1, C12H22O11. A document type is Article, introducing its new discovery.
A large number of new [Ru”([9]aneS3)(L)Cl]complexes (where L is a polypyridyl bidentate ligand) were synthesized from the precursor [Ru([9]aneS3)(dmso)Cl2] in the search for new DNA intercalators. The ancillary ligands used have different molecular architectures which include cross bridges, pyridyl units, phenanthroline and diamine derivatives. The related complex [Ru([9]aneS3)(ind)ClJ, containing the monodentate ligand indazole, was also prepared. The diimine complexes [Ru([9]aneS3)(pdi)Cl]+ and [Ru([9]aneS3)(phi)Cl]+ were prepared in situ from the ligands pda (o-phenylenediamine) and dap (phenanthrene-9, 10-diamine), respectively, via Ru assisted amine/imine oxidation. All complexes were characterised through ‘H NMR, IR, UV-Vis and electrospray mass spectrometry. Furthermore, the PF6 salts of seven [Ru([9]aneS3)(L)Cl]+ and [Ru([9]aneS3)(dip)Cl]BF4 (dip = 4, 7-diphenylphenanthroline) have been investigated by X-ray single crystal diffraction. The crystal structures are presented and analysed in terms of the molecular assemblies of the complex cations and anions and the molecular hydrogen bonding interactions. The ;t-stacking geometric arrangements of the extended aromatic systems dppz (dipyrido[3, 2-a:2′, 3’-c]phenazine) and dip in their metal complexes are also discussed. i The Royal Society of Chemistry 2000.
