SDS of cas: 1273-94-5, Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. In a document type is Article, and a compound is mentioned, 1273-94-5, name is 1,1′-Diacetylferrocene, introducing its new discovery.
Ferrocene-1,1′-diylbis(diphenylmethanol), , forms hydrogen-bonded host-guest adducts with a wide range of hydrogen-bond donors and acceptors.Adducts with a diol:guest ratio of 1:1 were formed by MeOH, EtOH, Me2SO, Me2NCHO, piperazine, and 4,4′-bipyridyl and 1:2 adducts by Me2SO, dioxane, pyridine and piperidine.The 1:1 adduct with MeOH has been shown to be triclinic, space group P<*> with a = 8.7624(3), b = 12.2797(6), c = 14.8773(8) Angstroem, alpha = 106.572(4), beta = 97.879(4), gamma = 100.873(4) deg with a final R of 0.044 for 4982 observed reflections.The structure consists of a centrosymmetric assembly of two molecules of diol and two molecules of the guest MeOH, hydrogen bonded together to form a chair conformation (OH)6 ring.The 1:2 adduct with pyridine has been shown to be monoclinic, space group C2/c with a = 16.6252(10), b = 11.1016(9), c = 20.9440(16) Angstroem, beta = 107.855(6) deg with a final R of 0.042 for 3260 observed reflections.In the structure the diol lies on a two-fold rotation axis with its hydroxyl hydrogens disordered and participating in both intramolecular O-H…O and intermolecular O-H…N hydrogen bonding with the two pyridine guest molecules.
