In the title rhenium(I) complex, [ReBr(C13H9N3O)(CO)3]·CH2Cl2, the dichloromethane solvent molecule is disordered over two positions with an occupancy ratio of 0.81 (15):0.19 (15). The ReI atom is coordinated by two N atoms from a 2-phenyl-5-(pyridin-2-yl-κN)-1,3,4-oxadiazole (L) ligand, three C atoms from three carbonyl groups and a Br atom in a distorted octahedral geometry. The three rings in L are almost coplanar (a mean plane fitted through all non-H atoms of this ligand has an r.m.s. deviation of 0.063 Å), and the carbonyl ligands are coordinated in a fac arrangement.
