Abstract
In the title compound, C15H17N2 +·Br−, the cyclobutene and benzene rings are coplanar. The dihedral angle between the benzene and imidazolium rings is 21.2 (3)°. In the crystal structure, the C15H17N2 + and Br− ions are linked into a zigzag chain along the b axis by C—H⋯Br hydrogen bonds, and weak C—H⋯π interactions involving the benzene ring of a screw-related cation.
Highlights
In the title compound, C15H17N2+ÁBrÀ, the cyclobutene and benzene rings are coplanar
The C15H17N2+ and BrÀ ions are linked into a zigzag chain along the b axis by C—HÁ Á ÁBr hydrogen bonds, and weak C—HÁ Á Á interactions involving the benzene ring of a screw-related cation
R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger
