New quinoline compound crystal form and preparation method thereof

The invention relates to a new quinoline compound crystal form and a preparation method thereof, and belongs to the field of pharmaceutical chemistry. The new crystal form X-ray powder diffraction diagram has peaks at the position of 2 theta of about 11.9, 12.9, 14.4, 16.0, 22.1 and 26.0 degrees; or the new crystal form X-ray powder diffraction diagram has peaks at the position of 2 theta of about 11.6, 14.1, 18.5, 21.1, 22.2, 23.2, 24.1 and 29.0 degrees. The new quinoline compound crystal form has good stability and liquidity, is beneficial to storage, transfer and production operation, and can be used for the preparation of pharmaceutically acceptable salts of the new quinoline compound crystal form for preparations.
