2-Diphenylphosphanyl-1-methyl-1H-benzimidazole

Abstract

In the title compound, C20H18N2P, the P atom is bonded to the two phenyl and imidazole groups, with an average P—C bond length of 1.828 (2) Å. The three C—P—C bond angles have values consistent with a tetrahedral geometry around the P atom with the fourth site occupied by a H atom. Crystal packing is through van der Waals interactions.
