The title compound [systematic name: 4,6-dichloro-N-(2-chlorophenyl)-1,3,5-triazin-2-amine], C9H5Cl3N4, is a triazine fungicide. The dihedral angle between the planes of the triazine and benzene rings is 4.04 (8)°. In the crystal, two weak C—H...N hydrogen bonds and short Cl...Cl contacts [3.4222 (4) Å] link adjacent molecules, forming two-dimensional networks parellel to the (112) plane. The planes are linked by weak intermolecular π–π interactions [3.6428 (5) and 3.6490 (5) Å], resulting in a three-dimensional architecture.

The molecular shape of the title compound, C16H12O7, is bent around the central CH2—O bond. The two benzene rings are almost perpendicular to one another, making a dihedral angle of 87.78 (7)°. In the crystal, each molecule is linked to three others by three pairs of O—H...O hydrogen bonds, forming undulating sheets parallel to thebcplane and enclosingR22(8) ring motifs. The sheets are linked by C—H...O hydrogen bonds and C—H...π interactions, forming a three-dimensional network.

In the title compound, C12H14N2O2S2, the dihydropyrimidine ring adopts a sofa conformation, with the C atom bearing the thienyl ring lying above the plane of the five remaining approximately coplanar (r.m.s. deviation = 0.0405 Å) atoms of the ring. The dihedral angle between the five near coplanar atoms of the ring and the thienyl ring is 89.78 (11)°. In the crystal, molecules are linked into a supramolecular chain along [100]viaN—H...O(carbonyl) hydrogen bonds. Inversion-related chains are linked into double chainsviaN—H...S(thione) hydrogen bonds. The three-dimensional architecture also features methyl–thienyl C—H...π interactions.

The title compound, C29H24N2OS, contains a phenothiazine moiety linked to a planar carbazole unit (r.m.s. deviation = 0.029 Å) by a C—C single bond. The phenothiazine moiety possesses a typical non-planar butterfly structure with a fold angle of 27.36 (9)° between the two benzene rings. The dihedral angle between the mean planes of the carbazole and phenothiazine units is 27.28 (5)°. In the crystal, molecules stack in pairs along thec-axis direction, linked by offset π–π interactions [intercentroid distance = 3.797 (1) Å]. There are C—H...π interactions present linking these dimers to form a three-dimensional structure.

In the title compound, C17H15NO4(alternative name;O-benzyl-L-tyrosineN-carboxy anhydride), the oxazolidine ring is planer, with an r.m.s. deviation of 0.039 Å. The benzyloxy and benzyl rings are almost coplanar, making a dihedral angle of 0.078 (10)°, and are inclined to the oxazolidine ring by 59.16 (11) and 58.42 (11)°, respectively. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen bonds, forming ribbons propagating along [010]. The ribbons are linked by C—H...π interactions, forming a three-dimensional supramolecular structure. The oxazolidine rings of adjacent ribbons are arranged into a layer parallel to theabplane. This arrangement is favourable for the polymerization of the compound in the solid state.

In the title compound, C15H10F2O2S, the dihedral angle between the planes of the benzofuran ring system [r.m.s. deviation = 0.015 (1) Å] and the 3-fluorophenyl ring is 26.60 (5)°. In the crystal, molecules are linked by C—H...O and C—H...F hydrogen bonds, and by π–π interactions between the benzofuran rings of inversion-related molecules [centroid(benzene)–centroid(furan) distance = 3.819 (2) Å], forming a three-dimensional network.

In the title compound, C20H20N2O3, the ten atoms comprising the quinazoline ring are essentially planar (r.m.s. deviation = 0.024 Å), and this plane is almost orthogonal to the terminal phenyl ring [dihedral angle = 82.87 (7)°]. The conformation about the ethylene bond [1.335 (2) Å] is E and there is a significant twist between this residue and the adjacent phenyl ring [C—C—C— torsion angle = −48.4 (3)°]. The crystal structure features centrosymmetric dimeric units linked by pairs of N—H...O hydrogen bonds between the amide groups which lead to eight-membered {...HNCO}2 synthons. These are consolidated into a three-dimensional architecture by C—H...O, C—H...π and π–π interactions [centroid–centroid distances = 3.5087 (8) and 3.5645 (9) Å].
