  In this paper we study A3560, a rich cluster at the southern periphery of the
A3558 complex, a chain of interacting clusters in the central part of the
Shapley Concentration supercluster.
  From a ROSAT-PSPC map we find that the X-ray surface brightness distribution
of A3560 is well described by two components, an elliptical King law and a more
peaked and fainter structure, which has been modeled with a Gaussian. The main
component, corresponding to the cluster, is elongated with the major axis
pointing toward the A3558 complex. The second component, centered on the
Dumb-bell galaxy which dominates the cluster, appears significantly offset (by
about 0.15 Mpc) from the cluster X-ray centroid.
  From a Beppo-SAX observation we derive the radial temperature profile,
finding that the temperature is constant (at kT~3.7 keV) up to 8 arcmin,
corresponding to 0.3 Mpc: for larger distances, the temperature significantly
drops to kT~1.7 keV. We analyze also temperature maps, dividing the cluster in
4 sectors and deriving the temperature profiles in each sector: we find that
the temperature drop is more sudden in the sectors which point towards the
A3558 complex.
  From VLA radio data, at 20 and 6 cm, we find a peculiar bright extended radio
source (J1332-3308), composed by a core (centered on the northern component of
the Dumb-bell galaxy), two lobes, a "filament" and a diffuse component. The
morphology of the source could be interpreted either with a strong interaction
of the radio source with the intracluster medium or with the model of
intermittency of the central engine.
