Due to previous X-ray non-detection, it was classified as soft X-ray weak QSO. We observed PG 1700+518 with XMM-Newton for about 60 ksec divided in three exposures. The spectrum below 2 keV is very steep, Gamma ~ 2.4-3.8, while at higher energies the extremely flat emission (photon index Gamma ~ 0.15, when modelled with a power law) suggests the presence of strong absorption (NH,pl ~ 2\\times10^23 cm-2, Gamma fixed to 1.8), or a reflection-dominated continuum.
