title: 2-(5,6-Di-hydro-benzimidazolo[1,2-c]quinazolin-6-yl)aniline methanol solvate.
abstract: In the structure of the title compound, C(20)H(16)N(4)·CH(4)O, the aniline ring forms dihedral angles of 89.9 (2) and 85.4 (2)° with the benzimidazole and benzene rings, respectively. The orientation of the aniline ring is mainly determined by strong hydrogen bonds between the amino group and the non-fused quinazoline N atom. Inter-molecular hydrogen bonds of the N-H⋯N-H⋯N type along [010] and the N-H⋯O-H⋯N type along [100] are formed, resulting in C(2) (2)(4) and C(2) (2)(10) descriptors, respectively, on a binary level of graph-set analysis. There are C-H⋯π contacts with H⋯π distances of 2.44 Å; however, no π-stacking is observed.
