摘要（英）：

The invention discloses a crystal form A of oxazolidinone antibacterial drug magnesium salt and a preparation method and application of the crystal form A. In an X-ray diffraction spectrum, the crystal form A has the characteristic peaks determined through the following 2theta reflection angles including 12.6+/-0.2 degrees, 16.8+/-0.2 degrees, 17.4+/-0.2 degrees, 18.9+/-0.2 degrees, 20.7+/-0.2 degrees, 21.5+/-0.2 degrees, 22.7+/-0.2 degrees, 24.3+/-0.2 degrees, 24.9+/-0.2 degrees, 26.4+/-0.2 degrees, 27.3+/-0.2 degrees, 28.2+/-0.2 degrees and 31.2+/-0.2 degrees. The crystal form A is good in stability and low in solvent residue, can be used for preparing a pharmaceutical composition and has the important application significance in preparation of antibiotic drugs.
