Abstract

The title compound, fac-[Re(C12H12N3)(CO)3]Br·0.5H2O, crystallizes with a cationic rhenium(I) unit, a bromide ion and half a water mol­ecule, situated on a twofold rotation axis, in the asymmetric unit. The ReI atom is facially surrounded by three carbonyl ligands and a tridentate bis­(pyridin-2-ylmeth­yl)amine ligand in a distorted octahedral environment. N—H⋯Br, O—H⋯Br, C—H⋯O and C—H⋯Br hydrogen bonds are present in the crystal structure and π–π stacking is also observed [centroid–centroid distances = 3.669 (1) Å and 4.054 (1) Å], giving rise to a three-dimentional network. The mol­ecules pack in a head-to-head fashion along the ac plane.
