Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. , Recommanded Product: 99-09-2, 99-09-2, Name is 3-Nitroaniline, molecular formula is C6H6N2O2, belongs to naphthyridine compound. In a document, author is Ismayilov, Rayyat Huseyn, introduce the new discover.
By using tetranaphthyridyl-triamine ligand, N-2-(2-(1,8-naphthyridin-7-ylamino)-1,8-naphthyridin-7-yl)-N-7-(1,8-naphthyridin-2-yl)-1,8-naphthyridine-2,7-diamine (H(3)tentra), double-stranded dinuclear helical compounds [M-2(H(3)tentra)(2)(ClO4)(4)] [M = Ni-II (1), Co-II (2), Fe-II (3), Zn-II (4)] were synthesized and structurally characterized. The single X-ray crystal structure of iron(II) complex showed that both of H(3)tentra ligands wrap around the metal-metal axis giving rise to a double-stranded dinuclear helical compound with Fe-Fe separation of ca. 5.326 angstrom. Each ligand uses two nitrogen atoms from two different napthyridine rings, to coordinate one metal centre (Fe or Fe(A)) and therefore, the geometry about the metal ions was described as distorted tetrahedral, with both ligands acting as bisbidentate N4 donors. This distortion is shown by the angles between nitrogen and iron atoms, which range from 80.45(15) to 143.32(14)degrees. Distorted tetrahedral environment was also proposed for the other complexes on the basis of the magnetic measurements and X-ray results. Strong pi-pi interactions were observed for all synthesized double stranded helicates of H(3)tentra ligand. The measured chi T-M values at 300 K for complexes 2 and 3 found larger than the expected values for two high-spin Co(II) with S = 3/2 and for Fe(II) ions with S = 2 and g = 2, which attributed to the unquenched orbital coupling.
