SYNTHESIS AND STRUCTURAL DETERMINATIONS OF ZINC(II) COMPLEXES CONTAINING DITHIOL AND N,N-HETEROCYCLIC LIGANDS

摘要

Syntheses and single crystal structural determinations of foul zinc complexes are presented: a mononuclear species, Zn(bdt)(biq); two binuclear species, [Zn(bdt)(phen)](2) and [Zn(tdt)(phen)](2) . 1,4-diphenyl-1,3-butadiene; and an unusual trinuclear species, Zn3(tdt)(3)(phen)(2), in which the zinc ions display either a four- or five-coordination geometry in a single molecule. The heterocyclic ligands used are 1,10-phenanthroline (phen) and biquinoline (big), and the dithiols are 1,2-benzenedithiol (bdt) and 3,4-dimercaptotoluene (tdt), Long range interactions dire to overlapping pi systems of the heterocycles are also indicated by the structures.
