N,N,N-Tri-butyl-butan-1-aminium (T-4)-(cyano-κC)tri-hydro-borate.
In the crystal structure of the title salt, C16H36N(+)·CH3BN(-), the tetra-n-butyl-ammonium cations and [BH3(CN)](-) anions are connected via weak C-H⋯N inter-actions, forming chains along the b-axis direction. The anion is almost linear with an N-C-B angle of 178.7 (2)°. The C-N-C angle values at the core of the tetra-n-butyl-ammonium cation range from 105.74 (11) to 111.35 (11)° with an average of 109.49 (11)°, close to the ideal tetra-hedral value.
