Abstract
Reaction between 3,4-diethyl-2,5-dimethyl-2,5-dihydro-1,2,5-thiadiborol (1, R = CH3) and (C5H5)Co(CO)2 yields the dark red. diamagnetic sandwich [(C5H5)Co(1)] (3, 92%). With [(C5H5)Ni(CO)]2 the green, paramagnetic complex [(C5H5)Ni(l)] (4, 57%) is obtained which at higher temperature forms nickelocene and Ni(1)2. 3 is easily reduced to the radical anion 3T. Neither 3 nor 4 can be stacked to give triple-decker complexes. The ESR spectra of the isoelec- tronic species 3T and 4 are reported.Keywords
