4-(2-Oxa-6-azaspiro[3.3]hept-6-yl)benzonitrile

4-(2-Oxa-6-aza­spiro­[3.3]hept-6-yl)­benzo­nitrile

In the title compound, C(12)H(12)N(2)O, the azetidine ring (r.m.s. deviation = 0.021 Å) and the oxetane ring (r.m.s. deviation = 0.014 Å) are nearly perpendicular to each other [dihedral angle = 89.7 (1)°]. The azetidine ring is twisted out of the plane of the benzene ring by 18.3 (1)°. In the crystal structure, mol-ecules are linked to form chains along the c axis by C-H⋯O hydrogen bonds.

6-Chloro-2-(4-meth­oxy­phen­yl)-4-phenyl­quinoline

In the title compound, C22H16ClNO, the quinoline ring system makes dihedral angles of 56.30 (6) and 7.93 (6)°, respectively, with the adjacent phenyl and benzene rings. The dihedral angle between these phenyl and benzene rings is 56.97 (8)°. In the crystal, weak C-H⋯π and π-π [centroid-centroid distances of 3.7699 (9) and 3.8390 (9) Å] inter-actions link the mol-ecules into a layer parallel to ...

2-(4-Chloro­phen­yl)-6-meth­oxy­chroman-4-one

In the title mol-ecule, C(16)H(13)Cl O(3), the two aromatic rings form a dihedral angle of 65.3 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed into columns propagating in [100] by weak C-H⋯π inter-actions.

6-(4-Amino­phen­yl)-2-meth­oxy-4-phenyl­nicotino­nitrile

In the structure of the title nicotino-nitrile derivative, C19H15N3O, the pyridine ring makes dihedral angles of 11.50 (7) and 43.36 (8)° with the 4-amino-phenyl and phenyl rings, respectively, and the dihedral angle between the phenyl rings is 36.28°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into wave-like sheets parallel to (10-2). These sheets are stacked by π-π inter-ac...
