The title compound, C10H16N4, crystalizes with two molecules (A and B) in the asymmetric unit in which the dihedral angles between the piperidine and pyrimidine rings are 47.5 (1) and 10.3 (1)°. The four C atoms of the pyrimidine ring in one of the molecules are disordered over two sets of sites with occupancy factors 0.508 (11):0.492 (11). In the crystal, the A molecules are linked to one another through N—H
N hydrogen bonds, generating R22(8) ring patterns and forming inversion dimers. These dimers are further connected on either side to a B molecule through pairs of N—HN hydrogen bonds, resulting in a tetrameric unit.

In the title compound, C26H22F2O2, the cyclopropane ring makes dihedral angles of 47.6 (2), 51.3 (2) and 63.9 (2)° with the 2-fluoro-substituted phenyl ring, the unsubstituted phenyl ring and the 4-fluoro-substituted phenyl ring, respectively. There is a short C—HF contact in the molecule. In the crystal, weak C—HF hydrogen bonds lead to chains of molecules extending along the b-axis direction.

In the title compound, C26H22ClFO2, the cyclopropane ring makes dihedral angles of 45.7 (2), 49.0 (2) and 65.2 (2)° with the fluoro-substituted phenyl ring, the benzene ring and the chloro-substituted phenyl ring, respectively. The F and Cl atoms deviate by 0.0307 (11) and 0.0652 (6) Å, respectively, from the planes of the phenyl rings to which they are attached. In the crystal, molecules are linked by C—HF hydrogen bonds, forming chains along the b axis.

The asymmetric unit of the title compound, C18H14ClNO3, contains two independent molecules (A and B). In both molecules, the cyclohexanone ring has a chair conformation. The dihedral angles between the pyran ring and the pyridine and chlorophenyl rings are 2.13 (9) and 2.19 (9)°, respectively, in A, and 0.82 (9) and 1.93 (9)°, respectively, in B. The carbonyl O atoms deviate from the pyran and benzene rings to which they are attached by −0.092 (2) and 0.064 (2) Å, respectively, in A, and by −0.080 (2) and −0.063 (2) Å, respectively, in B. In the crystal, the A molecules are linked via C—HO hydrogen bonds, forming double-stranded chains along [100]. They lie parallel to the double-stranded chains formed by the B molecules, which are also linked via C—HO hydrogen bonds. The chains stack up the c axis in an –A–A–B–B–A–A– manner, with a number of π–π interactions involving A and B molecules; the centroid–centroid distances vary from 3.4862 (11) to 3.6848 (11) Å

In the title compound, C18H15NO3, the fused benzopyran and pyridine rings are essentially coplanar [r.m.s. deviation = 0.0533 Å with a maximum deviation of 0.080 (1) Å for a benzene C atom]. The cyclohexanone ring adopts an envelope conformation with the dimethyl-substituted C atom 0.660 (2) Å out of the plane formed by the remaining ring atoms (r.m.s. deviation = 0.0305 Å). The dihedral angle between the mean planes of the pyran and cyclohexanone rings is 12.95 (6)°. In the crystal, molecules are linked via C—HO hydrogen bonds, leading to chains running along [011].
