A series of three homoleptic, monoanionic gold dithiolene complexes of oligothiophene ligands which coordinate via a central thiophene-3,4-dithiolate chelate are presented. The oligomer chains are three, five and seven thiophenes long and the complexes display hybrid optoelectronic properties featuring characteristics of both the oligothiophene chains and the delocalised metal dithiolene centre. The properties of the complexes have been characterised using a variety of spectroscopic and electrochemical methods complemented by computational studies. Solid state spectroelectrochemistry has revealed that upon oxidation these complexes display intense and broad absorption across the visible spectrum. In attempting to produce nickel analogues of these materials a single crystal of a photo-oxidised nickel dithiolene complex has also been isolated.

1,3-Dithiol-4,5-dithiolate and 5,6-Dihydro-1,4-diselenin-2,3-dithiolate Nickel Complexes

With the goal of obtaining new ethylenedithiolate transition metals complexes, unstable tetrabutylammonium bis(1,3-dithiol-4,5-dithiolato)niccolate(III) and stable tetrabutylammonium bis(5,6-dihydro-1,4-diselenin-2,3-dithiolato)niccolate(III) were synthesized. The two complexes were characterized by elemental analysis and IR and electron absorption spectroscopy, and the second, also by voltammetry. A new convenient procedure was proposed for preparation of 1,3-dithiol-2-thione which is a key initial compound in the synthesis of the title complexes.

Dithia- and dioxa-germoles: (X=S, O), have been prepared from diorganodihalogermanes and R'(NaS)C=C(SNa)R', 1,2-benzenedithiol, α-hydroxy ketones, R''(KO)C=C(OK)R'' or dioxastannole and by cleavage of Ge-N bonds of diorganobis(diethylamino)germanes by benzoin.The synthesis of spirobidithiagermoles is also reported.The thermal stability of dithiagermoles has been studied.Decomposition occurs mostly by a ring opening with formation of germathiones.In the presence of tertiary amines, dioxagermoles lead to germylenes and α-diketones through a ring opening.The chemical reactivity of dithia- and dioxa-germoles has been studied.Exchange reactions with dihalogenated covalent compounds occur readily leading to carbon, phosphorus and sulfur dithiole and dioxole analogs.From dichlorogermylene new stable functional cyclic germylenes are obtained and characterized.
