The electrochemical behavior and electrogenerated chemiluminescence (ecl) of Mo/sub 2/Cl/sub 4/(PMe/sub 3/)/sub 4/ in tetrahydrofuran and acetonitrile solutions have been investigated. Oxidation to the +1 cation and reduction to the -1 anion occur in quasi-reversible and reversible cyclic voltammetric waves, respectively. The oxidation product undergoes a subsequent chemical reaction, while the reduction product is stable. Emission is produced by the electron-transfer reaction between the +1 and -1 species; this emission is characteristic of /sup 1/(deltadelta/sup */) Mo/sub 2/Cl/sub 4/(PMe/sub 3/)/sub 4/ with emission lambda/sub max/ 680 nm. The ecl efficiency (photons produced per electron consumed) is 0.002. Electrogenerated chemiluminescence has been observed in acetonitrile solution by the reaction of electrogenerated Mo/sub 2/Cl/sub 4/(PMe/sub 3/)/sub 4//sup -/ with the strongly oxidizing intermediate, SO/sub 4//sup -/, generated by reduction of S/sub 2/O/sub 8//sup 2 -/.
