In the crystal structure of the title compound, [Cu2Br2(C9H14N2S)2], the mol­ecule resides about a crystallographic inversion center. The coordination sphere around each copper ion has a distorted tetra­hedral geometry, with ligation by two bridging bromide ions, an amine N atom and an imine N atom. The thio­phene ring is disordered over two sites, with occupancies of 0.719 (3) and 0.281 (3). Weak C—H⋯π inter­actions feature in the crystal packing.
