The ReI atom in the title methanol solvate is coordinated octa­hedrally by two N atoms of the chelating organic ligand, one Br atom and three facially configured carbonyl ligands. Hydrogen bonds between the complex and methanol solvent mol­ecules lead to a layered arrangement in the structure.

The synthesis of a new complex Re I (CO) 3 (HL)Br, where HL is ethyl 3-(2-pyridin-2-yl)-1H-1,2,4-triazole-5-carboxylate, is described in this work.
