Abstract

In the title compound, (C(8)H(20)N)[ReBr(C(5)H(7)O(2))(CO)(3)], the Re(I) atom in the rhenate anion is surrounded by three carbonyl ligands orientated in a facial arrangement, a bromide ligand and an acetyl-acetonate ligand, leading to a distorted octa-hedral ReC(3)BrO(2) coordination with a O-Re-O bite angle of 85.66 (7)°. An array of C-H⋯O and C-H⋯Br hydrogen-bonding inter-actions between the cations and the surrounding rhenate anions stabilize the crystal structure.
