Abstract:
The invention relates to the field of pharmaceutical chemistry, particularly relates to an orbit azine-fumarate, a hydrate, a crystal form, and a preparation method therefor. Specifically, in the invention, different crystal forms of orbit azine-fumarate, an orbit azine-fumarate hydrate and a crystal form thereof, and an amorphous form of orbit azine-fumarate are prepared by adjusting the ratio of orbit azine and fumaric acid and using different crystallization methods. The invention makes it possible to provide an orbit azine-fumarate which has a higher pharmaceutical effect, is easier to be prepared, and has a better storage stability.

Claim (Index 2):
The crystal form according to  claim 1 , which has an X-ray powder diffraction pattern comprising peaks at least at the following 20 positions: 5.9\u00b10.2, 16.8\u00b10.2 and 18.1\u00b10.2, as determined by using Cu-K\u03b1 radiation,\n optionally, the X-ray powder diffraction pattern further comprising at least one peak at a 2\u03b8 position selected from: 10.1\u00b10.2, 14.2\u00b10.2 and 22.4\u00b10.2, or at least one peak at a 2\u03b8 position selected from: 11.41\u00b10.2, 20.8\u00b10.2 and 23.8\u00b10.2.
