The structure is that of a trimeric isoquinoline. A dihydro_x0002_chloride is obtained as the dihydrate, m.p. 228- 232°C (dec.); the diperchlorate has m.p. 214-7°C; the oxalate forms a crystalline dihydrate, m.p. 158-163°C (dec.) on rapid heating and m.p. 198- 200°C (dec.) on slow heating. The O-acetate has m.p. 186°C and the methyl ether exists in two forms as crystals from AcOEt, m.p. 133-5°C and crystals from hexane which melt at 92-105°C and again at I 53-5°C after intermediate solidification. The structure has been determined by chemical degradation and spectroscopic analysis.
