We present an 82 ksec Chandra ACIS-I observation of a large-scale hierarchical complex , which consists of various clusters/groups of galaxies and low-surface brightness X-ray emission at z = 0.247 .
This high-resolution Chandra observation allows us for the first time to separate unambiguously the X-ray contributions from discrete sources and large-scale diffuse hot gas .
We detect 99 X-ray sources in a 17 ^ { \prime } \times 17 ^ { \prime } 
field .
Ten of these sources are identified as members of the complex and are mostly radio-bright .
Whereas unresolved X-ray sources tend to be associated with galaxies in intermediate density environments , extended X-ray emission peak at bright radio galaxies in the central cluster .
In particular , a distinct X-ray trail appears on one side of the fast-moving galaxy C153 , clearly due to ram-pressure stripping .
The diffuse X-ray emission from the central cluster can be characterized by a thermal plasma with a characteristic temperature of 3.2 _ { -0.4 } ^ { +0.5 } keV and a heavy element abundance of 0.24 _ { -0.12 } ^ { +0.15 } solar ( 90 % confidence uncertainties ) .
In comparison , a patch of low-surface brightness X-ray emission apparently originates in relatively low density intergalactic gas with a characteristic temperature of 0.98 _ { -0.27 } ^ { +0.22 } keV and an abundance of \lesssim 0.09 solar .
The Chandra observation , together with extensive multi-wavelength data , indicates that the complex represents a projection of several galaxy sub-structures , which may be undergoing major mergers .
We discuss the dynamic states of the complex and its sub-structures as well as properties of X-ray-emitting galaxies and the relationship to their environments .
