Metallkomplexe von N‐substituierten 3‐Imino‐isoindolinonen

Abstract

Metal Complexes of N‐substituted 3‐Imino‐isoindolinones The condensation of 3‐imino‐isoindolinone 4 and benzimidazoles or benzthiazoles containing activated methyl‐, methylen‐ or aminogroups ( 5 resp. 6 ), yields the iso‐indolinone‐ligands 1 and 2. Metal ions such as Co 2+ , Ni 2+ , Cu 2+ and Zn 2+ form (1:2)‐complexes with these ligands of very high chemical and photochemical stabilities. The magnetic properties of these complexes indicate that the geometry around the central atoms is distorted tetrahedral. A X‐ray diffraction study of one of the Co(II)‐complexes confirms these findings.
