The asymmetric unit of the title salt, (C7H11N2)2[CuCl4], comprises half a tetrahedral tetrachloridocuprate anion, being located on a twofold axis, and a protonated 4-(dimethylamino)pyridine cation. The geometry around the CuII ion is highly distorted with the range of Cl—Cu—Cl angles being 94.94 (1)–141.03 (1)°. The crystal structure is stabilized by N—H
Cl and C—HCl hydrogen bonds. In the three-dimensional network, cations and anions pack in the lattice so as to generate chains of [CuCl4]2− anions separated by two orientations of cation layers, which are interlocked through π–π stacking contacts between pairs of pyridine rings, with centroid–centroid distances of 3.7874 (7) Å.

In the title compound, C20H15ClN2, the pyrimidine ring is in a flattened half-chair conformation. The phenyl and chloro-substituted benzene rings form dihedral angles of 84.97 (5) and 80.23 (4)°, respectively, with the benzene ring of the dihydroquinazoline group. The dihedral angle between the phenyl and chloro-substituted benzene rings is 61.71 (5)°. In the crystal, molecules are arranged in intersecting layers parallel to (101) and (-102), with N—HN hydrogen bonds linking molecules along [010]. In addition, a weak C—Hπ interaction is observed.

In the title compound, C24H18ClN3, the dihydroquinazoline and methyl-substituted quinoline benzene rings make a dihedral angle of 78.18 (4)° and form dihedral angles of 45.91 (5) and 79.80 (4)°, respectively, with the phenyl ring. The dihedral angle between the phenyl ring of dihydroquinazoline and the methyl-substituted benzene ring of quinoline is 78.18 (4)°. The crystal packing can be described as crossed layers parallel to the (011) and (0-11) planes. The structure features N—HN hydrogen bonds and π–π interactions [centroid–centroid distance between phenyl rings = 3.7301 (9) Å].
