Overlay between meloxicam (grey), MX·HBr (red) and MX·HCl (green), calculated with Mercury (Macrae et al., 2020BB6). The fits were carried out using atoms belonging to the 1,2-benzo­thia­zine core (14 atoms), while the amide and thia­zole groups were kept free. The r.m.s. deviations for the fits are better than 0.04 Å. For the structure of the neutral mol­ecule MX, which has been reported three times, refcode SEDZOQ was retained (Fabiola et al., 1998BB2), in order to have all models at room temperature. For clarity, halide anions are omitted, as well as H atoms bonded to C atoms. Note that in MX, the thia­zole ring is not protonated.
