We search for extended X-ray emission between the two nearby galaxy clusters Abell~3667 and Abell~3651, which are separated by a projected transverse distance of ${\\sim}13\\,\\mathrm{Mpc}$, using data from the SRG/eROSITA All-Sky Survey. We performed a detailed X-ray image analysis of the region between the two galaxy clusters and conducted a redshift analysis of the sources between them.
