| Popis: | Several isomers are possible when N4-tetradentate ligands coordinate to form metal complexes. Here we report the synthesis and structural analysis of cis-β-{[1,6-di(2′-pyridyl)(2,5-dibenzyl-2,5-diazahexane)(1,2-benzoquinone diimine)]ruthenium(II)} formed exclusively from the β-precusor, β-{[1,6-di(2′-pyridyl)(2,5-dibenzyl-2,5-diazahexane) (dimethylsulfoxide)chloride] ruthenium(II)} hexaflourophosphate. Ruthenium(II) complexes synthesised from 1,6-di(2′-pyridyl)-2,5-dibenzyl-2,5-diazahexane, produce only two isomers which can be separated by recrystallisation into α- and β-[Ru(picenbz2)(dmso)Cl]PF6 (where picenbz2 is 1,6-di(2′-pyridyl)-2,5-dibenzyl-2,5-diazahexane). The distinctively different proton NMR spectra of the isomers are an especially convenient feature with which to assess separation. Isomeric structure of the precursor, α or β, is conserved upon coordination of a bidentate ligand, such as benzene-1,2-diamine, 4,5-dimethyl-benzene-1,2-diamine, naphthalene-2,3-diamine, 2,2′-bipyridine, 1,10-phena... |
