چکیده
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 π-π inter-action [interplanar distance = 3.38 (1) Å] with the neighboring biquinoline ligand.
