1-(2-Phenyl­benz­yl)-3-(2,4,6-trimethyl­benz­yl)imidazolidinium bromide

In the title salt, C(26)H(29)N(2) (+)·Br(−), which may serve as a precursor for N-heterocyclic carbenes, the imidazolidine ring adopts a twist conformation with a pseudo-twofold axis passing through the N—C—N carbon and the opposite C—C bond. The N—C—N bond angle [113.0 (4)°] and C—N bond lengths [1...

Sumario:In the title salt, C(26)H(29)N(2) (+)·Br(−), which may serve as a precursor for N-heterocyclic carbenes, the imidazolidine ring adopts a twist conformation with a pseudo-twofold axis passing through the N—C—N carbon and the opposite C—C bond. The N—C—N bond angle [113.0 (4)°] and C—N bond lengths [1.313 (6) and 1.305 (6) Å] confirm the existence of strong resonance in this part of the mol­ecule. In the crystal, a C—H⋯Br inter­action is present. The dihedral angle between the biphenyl rings is 64.3 (2)° and the phenyl rings make angles of 76.6 (3) and 18.5 (3)° with the plane of the imidazolidine ring.
