Azimines. III.Teilweise vorgetragen in Bern an der Jahresversammlung der Schweizerischen Gesellschaft für Kristallographie, 7.Oktober 1977, und als Autoreferat veröffentlicht [2]. Crystal structure of (1E,2Z)- and (1Z,2E)-2,3-dimethyl-1-phthalimido-azimine Teilweise aus der Diplomarbeit von R. M., ETH Zürich 1977.The structures of two diastereoisomeric 2,3-dimethyl-1-phthalimido-azimines, obtained by addition of phthalimido-nitrene to (E)-azomethane, have been determined by X-ray analysis. The major adduct 2a forms rhombic (space group Cmc21), the minor one 2b triclinic crystals (space group Pl). The molecular structures of 2a and 2b in the crystal exhibit several interesting features: (1) The azimines 2a and 2b are true dipolar systems with a coplanar skeleton and with bond angles of about 120°. Thus both azimine N,N bonds are potentially stereogenic centers; (2) 2a and 2b differ in configuration at both of these centers: 2a has
