On Dec. 2005 the bright Sy1.9 MGC-5-23-16 has been target of simultaneous and deep X-ray observations with all the major observatories. The energy resolution and the broad bandpass covered with this X-ray campain allowed us to conduct a spectral variability study as well as an investigation of the complex profile of the broad Fe K alpha emission line. We show the main results on the different components of the Fe line and their variability with respect to the flux variability of the source.
