6-(2-Hydroxy-phen-yl)-5,6-dihydro-benzimidazolo[1,2-c]quinazolin-12-ium bromide ethanol solvate.


ABSTRACT: In the title compound, C(20)H(16)N(3)O(+)·Br(-)·C(2)H(6)O, the phenol ring forms dihedral angles of 84.5?(1) and 89.3?(1)° with the benzimidazole system and the quinazoline benzene ring, respectively. The two N-H groups act as donors in hydrogen bonds with the bromide ion as acceptor, leading to infinite eight-membered chains along [100]. According to graph-set theory the descriptor on the binary level is C(2) (1)(8). O-H?O and O-H?Br hydrogen bonds also occur.

In the title compound, C(20)H(16)N(3)O(+)·Br(-)·C(2)H(6)O, the phenol ring forms dihedral angles of 84.5 (1) and 89.3 (1)° with the benzimidazole system and the quinazoline benzene ring, respectively. The two N-H groups act as donors in hydrogen bonds with the bromide ion as acceptor, leading to infinite eight-membered chains along [100]. According to graph-set theory the descriptor on the binary level is C(2) (1)(8). O-H⋯O and O-H⋯Br hydrogen bonds also occur. ...[more]
