Abstract
The crystal structure of bis-(p-Ethoxycarbonylphenylamino-methane (1) has been determined by single crystal X-ray diffraction analysis. The bis-aminal (1) molecule is V-shaped and situated on a twofold axis passing through C1 with the phenyl rings forming a dihedral angle of 70.2(1). The carboxylate and phenyl groups are coplanar. The crystal structure of 1 is compared with the structure of the closely related aminals, 2–5. Crystal data: 1 C19H22N2O4, tetragonal, space group I41cd (N.110), a = 20.4760(7) A ˚ ´,b = 20.4760(7) A ˚ ´,c = 8.2984(3) A ˚ , and V = 3477.7(2) A ˚ 3, for Z = 8.File in questo prodotto:
