Chloridobis[2-(1,3-thia­zol-4-yl-κN)-1H-benzimidazole-κN³]cobalt(II) chloride dihydrate

In the title compound, [CoCl(C₁₀H₇N₃S)₂]Cl·2H₂O, the Co^II atom is five-coordinated by four N atoms from two chelating 2-(1,3-thia­zol-4-yl)-1H-benzimidazole ligands and one Cl atom in a distorted trigonal–bipyramidal geometry. In the crystal, N—H...O and O—H...Cl hydrogen bonds and π–π inter­actions between the thia­zole, imidazole and benzene rings [centroid-to-centroid distances 3.546 (2), 3.683 (2) and 3.714 (2) Å] link the complex cations, chloride anions and uncoordinating water mol­ecules into a three-dimensional network.

[μ-2,2′-(1,4-Phenyl­ene)diacetato-κ²O¹:O⁴]bis­[aqua­(2,2′-bipyridine-κ²N,N′)chloridocopper(II)] dihydrate

In the centrosymmetric title compound, [Cu₂(C₁₀H₈O₄)Cl₂(C₁₀H₈N₂)₂(H₂O)₂]·2H₂O, the Cu^II atom is five-coordinated in a distorted square-pyramidal geometry by two N atoms from a chelating 2,2′-bipyridine ligand, one O atom from a 1,4-phenyl­enediacetate ligand, one Cl atom and one water mol­ecule. The 1,4-phenyl­enediacetate ligand, lying on an inversion center, bridges two Cu^II atoms. In the crystal, O—H...O and O—H...Cl hydrogen bonds and π–π inter­actions between the pyridine rings [centroid–centroid distance = 3.740 (5) Å] link the complex mol­ecules and uncoordinated water mol­ecules into a three-dimensional network.
