Abstract	The key to find genuine unabsorbed Seyfert 2s., excluding variability issues,is to perform simultaneous X-ray and optical spectroscopy. A campaign ofsimultaneous X-ray and optical observations of unabsorbed Seyfert 2s has alreadyproved successful in previous XMM-Newton AOs, leading to the discovery of thefirst unambiguous object of this new class (NGC3147: Bianchi et al., 2008). Withthe current proposal, we want to test completely different luminosity regimes,observing with XMM-Newton two unabsorbed Seyfert 2 candidates, Mrk273x andNGC4698. As already successfully done for the other targets allocated inprevious AOs to this program, we will organize simultaneous optical observationswith ground-based observatories.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
