The properties of unobscured AGN observed by XMM-Newton
  Multiwavelength analysis on large samples of AGN provides an excellent tool to understand the physics of these objects. We present the largest catalog of XMM-Newton targeted AGN, all with high SNR X-ray spectra. It includes all the radio-quiet objects observed by XMM-Newton, in targeted observations of the AGN panel. The principal X-ray properties of the catalog are complemented by multiwavelength data found in the literature (optical magnitudes, radio fluxes, Hbeta FWHM, BH masses). We present here some results on the correlation of these quantities. In particular, we find convincing evidence for an `Iwasawa effect' on the narrow component of the Fe Kalpha line and a correlation between the soft-to-hard X-ray luminosity ratio and the Hbeta FWHM.
