crystalline salts and derivatives: hydrochloride, m.p. 2S0-SoC (dec.); hydriodide,
m.p. 246-7°C (dec.); perchlorate, m.p. 2S4°C (dec.); aurichloride, m.p.
206°C (dec.); picrate, m.p. 230°C; picrolonate, m.p. 224-SoC (dec.) and the
methiodide which occurs in two modifications, m.p. 248°C and 267-276°C.
