The asymmetric unit of the title compound, [Cu(C7H4FO2)2(C6H6N2O)2(H2O)]·0.5C6H6N2O·3H2O, contains two aquabis(4-fluorobenzoato)bis(nicotinamide)copper(II) molecules, one nicotinamide solvent molecule and six water molecules. The CuII ion is coordinated by two O atoms from two 4-fluorobenzoate ligands, two N atoms from two nicotinamide ligands and one water O atom in a distorted square-pyramidal geometry. In the crystal, O—H
O, O—HN and N—HO hydrogen bonds consolidate the crystal packing, which also exhibits π–π interactions between the aromatic rings [centroid–centroid distances 3.692 (2)–3.794 (2) Å].

In the title compound, C12H11N3O2, the benzotriazole ring system is approximately planar [maximum deviation = 0.008 (1) Å] and its mean plane is oriented at a dihedral angle of 24.05 (4)° with respect to the furan ring. In the crystal, O—HN hydrogen bonds link the molecules into chains along the ac diagonal. π–π stacking between the furan rings, between the triazole and benzene rings, and between the benzene rings [centroid–centroid distances = 3.724 (1), 3.786 (1) and 3.8623 (9) Å] are also observed.

In the title compound, C19H15Cl2N3O2, the benzotriazole ring system is approximately planar [maximum deviation = 0.018 (2) Å] and its mean plane is oriented at dihedral angles of 30.70 (5) and 87.38 (4)°, respectively, to the furan and benzene rings while the dihedral angle between furan and benzene rings is 74.46 (6)°. In the crystal, weak C—HN hydrogen bonds link the molecules into chains along the b axis. π–π stacking interactions between the parallel dichlorobenzene rings of adjacent molecules [centroid–centroid distance = 3.6847 (9) Å] and weak C—Hπ interactions are also observed.
