Quality Control of 4-(p-Tolyl)-2,2:6,2-terpyridine. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 4-(p-Tolyl)-2,2:6,2-terpyridine, is researched, Molecular C22H17N3, CAS is 89972-77-0, about Homoleptic and heteroleptic complexes of chromium(III) containing 4′-diphenylamino-2,2′:6′,2”-terpyridine ligands. Author is Schonle, Jonas; Constable, Edwin C.; Housecroft, Catherine E.; Prescimone, Alessandro; Zampese, Jennifer A..

Two heteroleptic bis(2,2′:6′,2”-terpyridine)chromium(III) complexes [Cr(1)(4′-(4-tolyl)tpy)][CF3SO3]3 and [Cr(2)(4′-(4-tolyl)tpy)][CF3SO3]3 (1 = 4-([2,2′:6′,2”-terpyridin]-4′-yl)-N,N-diphenylaniline, 2 = 4-([2,2′:6′,2”-terpyridin]-4′-yl)-N,N-bis(4-methoxyphenyl)aniline, 4′-(4-tolyl)tpy = 4′-(4-tolyl)-2,2′:6′,2”-terpyridine) have been prepared and their spectroscopic and electrochem. properties compared with those of [Cr(4′-(4-tolyl)tpy)2][CF3SO3]3 and [Cr(1)2][CF3SO3]3. The single crystal structure of [Cr(4′-(4-tolyl)tpy)2][CF3SO3]3·2MeCN is presented, and the effects of accommodating three triflate anions and two MeCN mols. per cation are discussed in terms of related structures. The coordination of 1 or 2 to chromium(III) red shifts the intra-ligand charge transfer (ILCT) band and this band exhibits a neg. solvatochromic effect in some solvents. However, in H2O, MeOH, DMSO and DMF, the tpy ligands are labile; changes in the absorption spectra of solutions of [Cr(2)(4′-(4-tolyl)tpy)][CF3SO3]3 are consistent with the formation of [Cr(4′-Xtpy)(Solv)3]3+ (Solv = solvent) rather than complete ligand displacement or a ligand redistribution.
