In the crystal structure of the title compound, C20H21N3O, intra­molecular C—H⋯N hydrogen bonds stabilize the conformation of the mol­ecule. [ABSTRACT FROM AUTHOR]

In the title compound, C23H16N2O4, the mol­ecules form a supramolecular structure via inter­molecular C—H⋯O hydrogen bonds and inter­molecular π–π inter­actions. [ABSTRACT FROM AUTHOR]

In the title compound, C17H25N3OS, the mean plane of the imidazolinone system makes a dihedral angle of 83.07 (1)° with the phenyl ring. The crystal packing is stabilized by intermolecular N—H...N and C—H...O hydrogen-bonding interactions. The hexyl group is disordered over two sites with approximate occupancy factors 0.7:0.3.

In the crystal structure of the title compound, C22H21N3O2, the packing of the mol­ecules is mainly governed by inter­molecular C—H⋯O hydrogen bonds and π–π inter­actions. [ABSTRACT FROM AUTHOR]

In the crystal structure of the title compound, C17H23N3O3, intermolecular N—H⋯O and C—H⋯O hydrogen bonds are present. The planar heterocyclic ring makes a dihedral angle of 64.4 (1)° with the phenyl ring. [ABSTRACT FROM AUTHOR]

In the title compound, C19H16N6O4, all ring atoms in the triazolopyrimidinone unit are almost coplanar. The packing of the mol­ecules in the crystal structure is mainly due to inter­molecular C—H⋯O hydrogen-bonding inter­actions. [ABSTRACT FROM AUTHOR]
