(2-Amino­phen­yl)methyl­diphenyl­phospho­nium iodide

The asymmetric unit of the title compound, C19H19NP+·I−, contains two tetraalkylphosphonium cations and two I− anions. The P atoms are four-coordinated in distorted tetrahedral configurations by three phenyl and one methyl C atoms. There are weak intra- and intermolecular N—H⋯I contacts.

6-(2-Fluoro­phen­yl)-5,6-dihydro­benzimidazolo[1,2-c]quinazoline

In the title compound, C20H14FN3, the pyrimidine ring adopts a half-chair conformation. The dihedral angle between the benzimidazole ring system and the fluorophenyl ring is 84.18 (10)°. In the crystal structure, molecules are linked into a two-dimensional network parallel to the bc plane by N—H⋯N and C—H⋯F hydrogen bonds.
