Most dithiolene complexes are prepared by reaction of alkali metal salts of 1,2-alkenedithiolates with metal halides. A thiolate is the conjugate base of a thiol, so alkenedithiolate is, formally speaking, the conjugate base of an alkenedithiol. Common alkenedithiolates are 1,3-dithiole-2-thione-4,5-dithiolate and maleonitriledithiolate (mnt ): WebThree hexacarbonyl diiron dithiolate complexes [Fe2(CO)6(µ-(SCH2)2X)] with different substituted bridgeheads (X = CH2, CEt2, CBn2 (Bn = CH2C6H5)), have been studied under the same experimental conditions by cyclic voltammetry in dichloromethane [NBu4][PF6] 0.2 M.
