Crystal structure of bis(1-mesityl-1H-imidazole-κN3)diphenylboron trifluoromethanesulfonate

Abstract

The solid-state structure of bis(1-mesityl-1H-imidazole-κN3)diphenylboron trifluoromethanesulfonate, C36H38BN4+·CF3SO3− or (Ph2B(MesIm)2OTf), is reported. Bis(1-mesityl-1H-imidazole-κN3)diphenylboron (Ph2B(MesIm)2+) is a bulky ligand that crystallizes in the orthorhombic space group Pbcn. The asymmetric unit contains one Ph2B(MesIm)2+ cationic ligand and one trifluoromethanesulfonate anion that balances the positive charge of the ligand. The tetrahedral geometry around the boron center is distorted as a result of the steric bulk of the phenyl groups. Weak interactions, such as π–π stacking are present in the crystal structure.
