32. Synthesis of compound 1: The 6, 7-qdt dianion is generated, in situ, by treatment with H2(6, 7-qdt) (0.060 g, 0.309 mmol) with NaOH (0.029 g, 0.725 mmol) in MeOH (10 mL) under nitrogen atmosphere. To the resulting clear red solution, NiCl2·6H2O (0.035 g, 0.15 mmol) was added; the resulting dark blue solution was stirred for 30 min. Dark blue micro crystals were precipitated by adding tetrabutylammonium bromide (0.1 g, 0.310 mmol); the micro crystals were filtered, washed with water followed by diethyl ether, and dried at room temperature. It was recrystallized from acetonitrile solution by vapor diffusion with diethyl ether. Yield: 0.116 g (83.3% based on Ni).
