Here we present the first case of a Compact Steep Spectrum (CSS) radio galaxy, 3C 305, in which the X-ray radiation appears to be associated with the optical emission line region, marked by the [O III]5007. On the basis of a morphological study, performed using the comparison between the X-rays (Chandra), the optical (HST) and the radio (VLA) data, we argue that the high energy emission has a thermal nature. Finally, we discuss the origin of the extended X-ray structure connected with the optical emission line region following two different interpretations: as due to the interaction between matter outflows and shock-heated environment gas, or as due to gas photoionized by nuclear emission.
