Cobalt(iii)-containing penta-dentate “helmet”-type phthalogens: synthesis, solid-state structures and their thermal and electrochemical characterization

Abstract

Treatment of unsubstituted and substituted phthalonitrile (1a–d) with appropriate equivalents of sodium methoxide and ammonia afforded the corresponding 1,3-diiminoisoindolines (2a–d), which were converted to cobalt(III)-containing penta-dentate “helmet”-type phthalogens (3a–d) by...
