dc.description.abstract The 2,3-disulfidothienoquinoxaline complexes of Cp2Mo and dppePd and the 2,3-disulfidothienopyridine complexes of Cp2Mo were obtained as products from the S8 oxidation of the corresponding metallo-1,2-enedithiolate complexes. The analogous 2-sulfido-3-oxidothienoquinoxaline complexes of Cp2Ti, Cp2Mo, dppPd, and dppePt were prepared from 1-(quinoxalin-2-yl)-2-bromoethanone and the corresponding polysulfido complex. Both Cp2Mo{S2C10H4N2S} and Cp2Mo{SOC10H4N2S} have been characterized crystallographically. These complexes contain an extended planar ring where the metal is bound to substituents at the 2- and 3-positions of the thiophene ring. The oxidation products of the Cp2Mo derivatives all have EPR g values near 1.98 and 97/95Mo hyperfine of </= 8.5 G. All of the complexes have a visible band assigned to an intraligand transition (IL). The excitation of a room-temperature DMSO solution of dppePt{SOC10H4N2S} leads to an emission at 690 nm with a = 0.005. Lifetime measurements were best fit as the sum of two exponential decays with lifetimes of 6 and 0.3 ns (Refer to PDF file for exact formulas). en_US
