In the title CoII complex, [Co(C5H3N2O4)2(H2O)4]·2H2O, the CoII ion is located on an inversion center and is coordinated by two orotate (2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) anions and four water molecules in a slightly distorted octahedral geometry. The dihedral angle between the carboxylate group and the attached orotate ring is 1.2 (3)°. In the crystal structure, intermolecular O—HO, N—HO and C—HO hydrogen bonds link the molecules into a three-dimensional network. π–π contacts between the orotate rings [centroid–centroid distances = 3.439 (2) and 3.438 (2) Å] further stabilize the structure.

The asymmetric unit of the title compound, C21H18ClN3O, contains two crystallographically independent molecules which differ slightly in the orientations of chlorobenzyloxy units. In one of the molecules, the phenyl and chlorophenyl rings are oriented at dihedral angles of 38.09 (6) and 42.15 (6)°, respectively, with respect to the benzotriazole ring [43.23 (6) and 29.80 (6)° in the other molecule]. The dihedral angle between the phenyl and chlorophenyl rings is 77.63 (6)° in one of the molecules and 72.97 (6)° in the other. The crystal structure is stabilized by weak C—Hπ interactions.

The title compound, C19H22N2O2S2, consists of a tetracyclic ring system containing an azocine skeleton with methoxyethyl and dithiolane groups as substituents. The benzene and five-membered N-heterocyclic rings are nearly coplanar, making a dihedral angle of 0.81 (12)°. The dithiolane ring adopts an envelope conformation. Intermolecular N—HO hydrogen-bonding and weak C—Hπ interactions are present in the crystal structure.
