✦ Synopsis
The title compound, C 4 H 12 N + ÁBr À , is a hydrolysis product of the 1-(dibromoboryl)ferrocene±dimethylethylamine (1/1) adduct. The metric symmetry is apparently orthorhombic Ccentred, but the intensity statistics indicate unambigously the correct Laue symmetry, viz. primitive monoclinic. The ethyl group is disordered over two sites. In addition to the hydrogen bond from the NH group to the Br À ion, the packing is stabilized by several weak CÐHÁ Á ÁBr hydrogen bonds.
