(2,2'-Biquinoline-?N,N')dibromido-zinc(II).

ABSTRACT: In the title compound, [ZnBr(2)(C(18)H(12)N(2))], the Zn(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the 2,2'-biquinoline ligand and two terminal Br atoms. The crystal packing is stabilized by weak inter-molecular C-H?Br hydrogen bonds and extensive inter-molecular ?-? contacts between the pyridine and benzene rings [centroid-centroid distances = 3.775?(4), 3.748?(4), 3.735?(4), 3.538?(4), 3.678?(4) and 3.513?(4)?Å].

In the title compound, [ZnBr(2)(C(18)H(12)N(2))], the Zn(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the 2,2'-biquinoline ligand and two terminal Br atoms. The crystal packing is stabilized by weak inter-molecular C-H⋯Br hydrogen bonds and extensive inter-molecular π-π contacts between the pyridine and benzene rings [centroid-centroid distances = 3.775 (4), 3.748 (4), 3.735 (4), 3.538 (4), 3.678 (4) and 3.513 (4) Å]. ...[more]

Bis-(benzene-thiol-ato)(2,2'-biquinoline)zinc(II).

Project description:The title compound, [Zn(C(6)H(5)S)(2)(C(18)H(12)N(2))], was prepared as a model for future complexes that will be incorporated into light-harvesting arrays. The Zn(II) atom lies on a twofold rotation axis and the ligands are arranged tetra-hedrally around this atom. The benzene-thiol-ate ligand and the biquinoline ligand are nearly perpendicular to one another, making a dihedral angle of 84.09?(5)°. The biquinoline ligand is nearly planar, with a maximum deviation of 0.055?(3)?Å from the mean plane of the ring system. In the crystal, the mol-ecules pack in a manner such that the biquinoline ligands are parallel to one another, with a ?-? inter-action [interplanar distance = 3.38?(1)?Å] with the neighboring biquinoline ligand.

Dibromido(2,2':6',2''-terpyridine-?N,N',N'')zinc(II).

Project description:In the title compound, [ZnBr(2)(C(15)H(11)N(3))], the Zn(II) ion is five-coordinated by the three N atoms from a 2,2':6',2''-terpyridine ligand (terpy) and two bromide anions in a distorted trigonal bipyramidal configuration.
