Synthesis of 5,5-diphenyl-3-(methylthiomethyl)hydantoin and 5,5-diphenyl-3-(methysulfonylomethyl)hydantoin

5,6-Diphenyl-3-(3-pyrid­yl)-1,2,4-triazine

In the mol-ecule of the title compound, C(20)H(14)N(4), the triazine ring is attached to two phenyl rings and one pyridine ring. In the crystal, mol-ecules are linked by inter-molecular C-H⋯N hydrogen bonds. The crystal packing is also stabilized by C-H⋯π inter-actions.

3-Ethyl­sulfanyl-2,5-diphenyl-1-benzofuran

In the title compound, C(22)H(18)OS, the 2-phenyl ring is rotated out of the benzofuran plane, making a dihedral angle of 29.18 (6)°. The dihedral angle between the 5-phenyl ring and the benzofuran plane is 20.42 (5)°. In the crystal structure, mol-ecules are linked by weak inter-molecular C-H⋯π inter-actions.

2-(3-Nitro­phen­yl)-4,5-diphenyl-1H-imidazol-3-ium chloride

The title compound, C(21)H(16)N(3)O(2) (+)·Cl(-), contains two organic cations with similar conformation and two chloride ions in the asymmetric unit. The imidazole and benzene rings are twisted with respect to each other [dihedral angles of 24.05 (16), 24.31 (16) and 50.38 (13) in one cation and 27.70 (15), 25.07 (16) and 45.86 (14)° in the other]. The crystal packing is stabilized by N-H⋯Cl h...

2-(3-Nitro­phen­yl)-4,5-diphenyl-1H-imidazol-3-ium nitrate

In the cation of the title compound, C(21)H(16)N(3)O(2) (+)·NO(3) (-), the N atom in the 3-position of the imidazole ring is protonated. The three pendant aromatic rings are twisted from the plane of the imidazolium ring by dihedral angles of 22.75 (1), 79.63 (1) and 29.65 (1)°. In the crystal structure, N-H⋯O hydrogen bonds link the mol-ecules, forming an infinite one-dimensional chain paralle...
