We present deep ROSAT X-ray images of the double nucleus galaxy Mrk 266 in combination with optical images and spectra. The High Resolution Imager (HRI) X-ray morphology can be divided into four components: two nuclei of the merging galaxies, a diffuse galactic component and a strong northern jet coincident with very strong optical line emission. This jet component is decoupled from the rest of the merging system considering the internal kinematics. The luminous X-ray jet is excited by hot postshock gas with respect to the morphology, the high excitation emission lines and the kinematics.
