Tetra­aqua­bis(orotato-κO)cobalt(II) dihydrate

In the title Co^II complex, [Co(C₅H₃N₂O₄)₂(H₂O)₄]·2H₂O, the Co^II 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—H...O, N—H...O and C—H...O 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.

1-[2-(4-Chloro­benz­yloxy)-2-phenyl­ethyl]-1H-benzotriazole

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—H...π inter­actions.

6,6-[Ethyl­enebis(sulfanediyl)]-2-(2-methoxy­ethyl)-1,2,3,4,5,6-hexa­hydro-1,5-methano-1H-azocino[4,3-b]indol-3-one

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—H...O hydrogen-bonding and weak C—H...π inter­actions are present in the crystal structure.
