(4,4′-Dimethyl-2,2′-bipyridine-κ2N,N′)(dimethylformamide-κO)diiodidocadmium

In the title compound, [CdI2(C12H12N2)(C3H7NO)], the CdII cation is five-coordinated in a distorted trigonal–bipyramidal configuration by two N atoms from a 4,4′-dimethyl-2,2′-bipyridine ligand, one O atom from a dimethylformamide ligand and two I− anions. π–π stacking between pyridine rings of adjacent molecules [centroid–centroid distance = 3.666 (3) and 3.709 (4) Å] stabilizes the three-dimensional structur

catena-Poly[[(4,4′-dimethyl-2,2′-bipyridine-κ2N,N′)cadmium]-di-μ-bromido]

In the crystal of the title polymeric compound, [CdBr2(C12H12N2)]n, the CdII cation is located on a twofold rotation axis and is six-coordinated in a distorted octahedral geometry formed by two N atoms from the 4,4′-dimethyl-2,2′-bipyridine ligand and by four bridging Br− anions. The bridging function of the Br− anions leads to a polymeric chain running along the c axis. Weak C—H...π interactions observed between adjacent chains are effective in the stabilization of the three-dimensional packing

Dibromido(6-methyl-2,2′-bipyridine-κ2N,N′)cobalt(II)

In the molecule of the title compound, [CoBr2(C11H10N2)], the CoII atom is four-coordinated in a distorted tetrahedral geometry by two N atoms from a chelating 6-methyl-2,2′-bipyridine ligand and two terminal Br atoms. In the crystal, π–π stacking interactions between the pyridine rings along the a-axis direction [centroid–centroid distance = 3.761 (7) Å] and C—H...Br hydrogen bonds in the bc plane together generate the three-dimensional packing

Trichlorido(5,5′-dimethyl-2,2′-bipyridine-κ2N,N′)(dimethylformamide-κO)indium(III) hemihydrate

The asymmetric unit of the title compound, [InCl3(C12H12N2)(C3H7NO)]·0.5H2O, contains two independent InIII complex molecules with similar structures and one lattice water molecule. In each complex molecule, the InIII atom is six-coordinated in a distorted octahedral geometry, formed by two N atoms from the chelating 5,5′-dimethyl-2,2′-bipyridine ligand, one O atom from a dimethylformamide and three facial Cl atoms. In the crystal, the lattice water molecule is linked to the complex molecules via O—H...Cl hydrogen bonds. Further weak C—H...Cl and C—H...O hydrogen bonds result in the formation of a three-dimensional structure

Di-μ-bromido-bis[bromido(4,7-diphenyl-1,10-phenanthroline-κ2N,N′)cadmium]

The title compound, [Cd2Br4(C24H16N2)2], consists of a centrosymmetric dimeric unit in which two Br atoms bridge two CdII atoms, forming a four-membered ring. A terminal Br atom and a bidentate chelating 4,7-diphenyl-1,10-phenanthroline ligand complete a square-pyramidal geometry for the CdII atom. In the crystal, C—H...Br hydrogen bonds and π–π contacts between the pyridine and phenyl rings [centroid–centroid distances = 3.704 (4) and 3.715 (4) Å] lead to a three-dimensional supramolecular structure
