(Analytical Sciences, 2007) Çelik, İsmail; Ersanlı, Cem Cüneyt; Akkurt, Mehmet; Demirtaş, İ.
The title compound, (C26H23N)3·CHCl3, was synthesized by the reaction of trityl bromide with m-toluidine in chloroform and crystalized in the trigonal R3 space group (Z = 6) with the one molecule of chloroform, and with a = 20.765(5), b = 20.765(5), c = 24.924(5)Å, ? = ? = 90°, ? = 120°, V = 9307(4)Å3, Z = 6 and Dx = 1.250 Mg m-3. A least-squares refinement gave a residual index of R = 0.065 for 3540 observed reflections. Three phenyl rings of the title compound are at angles of 60.39(13), 74.10(14) and 70.17(13)° to the six-membered ring of the planar aminophenol group. The dihedral angles between three phenyl rings are 73.60(16), 87.80(15) and 56.52(15)°.
