Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter.611-64-3, Name is 9-Methylacridine, SMILES is CC1=C(C=CC=C2)C2=NC3=CC=CC=C31, belongs to pyrrolines compound. In a document, author is Meyer, Andreas, introduce the new discover, Category: pyrrolines.
Crystal structure of 4 ‘-{[4-(2,2 ‘:6 ‘,2 ”-terpyridyl-4 ‘-yl)phenyl]ethynyl}biphenyl-4-yl (2,2,5,5-tetramethyl-1-oxyl-3-pyrrolin-3-yl)formate benzene 2.5-solvate
The title compound, C44H35N4O3 center dot 2.5C(6)H(6) (1), consists of a terpyridine and a N-oxylpyrroline-3-formate group separated by an aromatic spacer, viz. 4-(phenylethynyl)-1,1′-biphenyl. It crystallized in the triclinic space group P (1) over bar with two and a half benzene solvate molecules (one benzene molecule is located about an inversion center), while the dichloromethane solvate (2) of the same molecule [Ackermann et al. (2015). Chem. Commun. 51, 5257-5260] crystallized in the tetragonal space group P4(2)/n, with considerable disorder in the molecule. In (1), the terpyridine (terpy) group assumes an all-trans conformation typical for terpyridines. It is essentially planar with the two outer pyridine rings (B and C) inclined to the central pyridine ring (A) by 8.70 (15) and 14.55 (14)degrees, respectively. The planes of the aromatic spacer (D, E and F) are nearly coplanar with dihedral angles D/E, D/F and E/F being 3.42 (15), 5.80 (15) and 4.00 (16)degrees, respectively. It is twisted with respect to the terpy group with, for example, dihedral angle A/D being 24.48 (14)degrees. The mean plane of the N-oxylpyrroline is almost normal to the biphenyl ring F, making a dihedral angle of 86.57 (16)degrees, and it is inclined to pyridine ring A by 72.61 (15)degrees. The intramolecular separation between the O atom of the nitroxyl group and the N atom of the central pyridine ring of the terpyridine group is 25.044 (3) angstrom. In the crystal, molecules are linked by pairs of C-H center dot center dot center dot O hydrogen bonds, forming inversion dimers. The dimers stack along the c axis forming columns. Within and between the columns, the spaces are occupied by benzene molecules. The shortest oxygen-oxygen separation between nitroxyl groups is 4.004 (4) angstrom. The details of the title compound are compared with those of the dichloromethane solvate (2) and with the structure of a related molecule, 4′-{4-[(2,2,5,5-tetramethyl-N-oxyl-3-pyrrolin-3-yl)ethynyl]phenyl}-2,2′:6’,2 ”-terpyridine (3), which has an ethynylphenyl spacer [Meyer et al. (2015). Acta Cryst. E71, 870-874].
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 611-64-3 is helpful to your research. Category: pyrrolines.
