The title compound, [Cu2Cl4(C7H8N2O)2], crystallizes as discrete [CuLCl2]2 (L = 2-aminobenzamide) dimers with inversion symmetry. Each CuII ion is five-coordinated and is bound to two bridging chloride ligands, a terminal chloride ligand and a bidentate 2-aminobenzamide ligand. The crystal structure exhibits alternating layers parallel to (010) along the b-axis direction. In the crystal, the components are linked via N—HCl hydrogen bonds, forming a three-dimensional network. These interactions link the molecules within the layers and also link the layers together and reinforce the cohesion of the structure.

In the crystal structure of the title salt hydrate, C9H8NO+·HSO4−·H2O, the quinoline N—H atoms are hydrogen bonded to the bisulfate anions. The bisulfate anions and water molecules are linked together by O—HO hydrogen-bonding interactions. The cations and anions form separate layers alternating along the c axis, which are linked by N—HO and O—HO hydrogen bonds into a two-dimensional network parallel to (100). Further O—HO contacts connect these layers, forming a three-dimensional network, in which two R44(12) rings and C22(13) infinite chains can be identified.

In the title Schiff base salt, C16H13N2O+·ClO4−, the pyridine ring and the naphthalene ring system are approximately co-planar [making a dihedral angle of 6.05 (12)°] and an intramolecular O—HN hydrogen bond occurs between the hydroxyl and imino groups. In the crystal, the cations and anions are linked by N—HO and weak C—HO hydrogen bonds, forming the supramolecular layers parallel to (100). The crystal studied was an inversion twin refined with minor component = 0.43 (13).
