  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.
