Abstract: We report on an XMM-Newton observation of the Seyfert 1 galaxy Mrk 335 performed in 2000 December. The 0.3--10 keV spectrum of Mrk 335 is compared with X-ray spectra of a sample of Seyfert 1 galaxies that we analysed within the frame of the XMM-Newton Guaranteed Time Programme. The spectral components of Mrk 335 exhibit important specificities, i.e (i) their luminosity is variable on timescales as short as a few ksec, (ii) the power law component above 2 keV has a photon index much steeper than that of a "normal" Seyfert 1 galaxy, (iii) the spectral feature observed around 6.0 keV is broad and can be fitted by a relativistic emission profile and (iv) the soft excess above the power law rises steeply below 2 keV and represents more than 30 % of the intrinsic source luminosity in the 0.3--2 keV band. We present a scenario that could account for these spectral properties taking into account previous ASCA and SAX observations.
