The notion of using the Pt diimine dithiolate chromophore in a multicomponent system for light-driven reactions has stimulated the design and synthesis of related complexes having ligands capable of functioning as bridges. Complexes of one such ligand, dipyridocatecholate or phenanthroline-5,6-diolate, have recently been reported. In the present study, the dithiolate ligand is replaced by two thiolates having pyridyl groups for connection to another metal. The authors describe herein the synthesis, characterization, and X-ray structure determination of the resultant complex, Pt(dbbpy)(S-4-py){sub 2} (dbbpy = 4,4{prime}-di-tert-butyl-2,2{prime}-bipyridine, S-4-py = pyridine-4-thiolate). Diimine bis(thiolate) complexes of platinum(II) have not been studied as extensively as the corresponding dithiolate systems, but they appear to have a similar electronic structure with an intense solvatochromic absorption band in the visible region of the spectrum and an associated charge-transfer emission that is observable at 77 K.
