Dichloridobis[2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole-κN3]cadmium(II)

Dibromidobis(2-methyl-1H-benzimidazole-κN3)cadmium

In the title compound, [CdBr₂(C₈H₈N₂)₂], the Cd^II atom has a distorted tetra­hedral coordination formed by the two imino N atoms of two 2-methyl­benzimidazole ligands and two terminal bromide ligands. The Cd^II atom is slightly out of the benzimidazole planes by 0.320 (3) and 0.210 (3) Å. The dihedral angle between the benzimidazole planes is 71.6 (2)°. In the crystal, mol­ecules are linked by N—H⋯Br hydrogen bonds into puckered layers parallel to (001).

Bis[2-(2-fur-yl)-1-(2-furylmeth-yl)-1H-benzimidazole-κN]diiodidocadmium

In the title complex, [CdI₂(C₁₆H₁₂N₂O₂)₂], the Cd^II atom is located on a twofold rotation axis and is four-coordinated by two N atoms from symmetry-related 2-(2-fur­yl)-1-(2-furyl­meth­yl)-1H-benzimidazole ligands and two I atoms in a distorted tetra­hedral configuration. The benzimidazole rings in adjacent mol­ecules are parallel, with an average inter­planar distance of 3.486 Å. The I atom is disordered over two sites in a 0.85 (5):0.15 (5) ratio.

Bis{μ-1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole}bis-(iodido-cadmium)

The dinuclear title complex, [Cd(2)I(4)(C(12)H(13)N(5))(2)], lies on a crystallographic center of inversion. The Cd(II) atom is four-coordinated by two N atoms from two 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands and two terminal I atoms in a distorted tetra-hedral coordination environment. The Cd(II) atoms are connected to each other by two bridging bmei ligands. The benzotriazole rings in adjacent mol-ecules are almost parallel, with an average inter-planar distance of 3.3400 (2) Å and a centroid-centroid distance of 4.852 (2) Å.

Bis[4-(2-hydroxybenzylideneamino)benzoato-κO1]tetrakis(methanol-κO)cadmium

In the title mononuclear complex, [Cd(C₁₄H₁₀NO₃)₂(CH₃OH)₄], the Cd²⁺ cation is situated on an inversion centre. It exhibits a distorted octa­hedral coordination, defined by two carboxyl­ate O atoms from two monodentate anions and by four O atoms from four methanol mol­ecules. The crystal structure comprises intra­molecular O—H⋯O and O—H⋯N, and inter­molecular O—H⋯O hydrogen bonds. The latter help to construct a layered structure extending parallel to (100).
