In the title salt, (C(8)H(20)N)[ReBr(C(7)H(5)O(2))(CO)(3)], the Re(I) atom is octa-hedrally surrounded by three facially orientated carbonyl ligands, one bidendate tropolonate ligand and a bromide ligand. The small O-Re-O bite angle of 74.88 (12)° leads to a distortion of the octa-hedral coordination sphere. The bromide ligand and the axial carbonyl ligand are substitutionally disordered over two positions in a 0.922 (3):0.078 (3) ratio. An array of C-H⋯O and C-H⋯Br hydrogen-bonding inter-actions between the cations and neighbouring rhenate anions stabilizes the crystal packing.
在标题盐（C(8)H(20)N)[ReBr(C(7)H(5)O(2))(CO)(3)]中，铼（I）原子被三个面式排列的羰基配体、一个双齿环庚三烯酚酮配体和一个溴化物配体八面体包围。74.88 (12)°的小O-Re-O咬角导致八面体配位球发生畸变。溴化物配体和轴向羰基配体在两个位置上以0.922 (3):0.078 (3)的比例发生替代无序。阳离子与相邻铼酸盐阴离子之间的一系列C-H⋯O和C-H⋯Br氢键相互作用稳定了晶体堆积。
