Crystal structure of bis-(1-mesityl-1-imidazole-κ )di-phenyl-boron tri-fluoro-methane-sulfonate.

The solid-state structure of bis-(1-mesityl-1-imidazole-κ )di-phenyl-boron tri-fluoro-methane-sulfonate, CHBN ·CFSO or (), is reported. Bis(1-mesityl-1-imidazole-κ )di-phenyl-boron ( ) is a bulky ligand that crystallizes in the ortho-rhom-bic space group . The asymmetric unit contains one cationic ligand and one tri-fluoro-methane-sulfonate anion that balances the positive charge of the ligand. The tetra-hedral geometry around the boron center is distorted as a result of the steric bulk of the phenyl groups. Weak inter-actions, such as π-π stacking are present in the crystal structure.
