A cobalt complex with mixed valence state [Co( Ⅰ ) (dppe)2CO]2 [Co2 ( Ⅱ )(dppe) Cl]6O2] (dppe = 1,2 - bis(diphenylphosphino) ethane) has been prepared. The compound crystallizes in triclinic space group P1 with unit cell parameters: a=1. 1763(3) nm, b = 1. 2943(6) nm, c=2. 1507(9) nm, a=81. 44(4)°? ,β=82. 58(3)°, r = 79. 82(3)°, V = 3. 1691 nm3 and Z=1. The structure was solved by direct method according to ALPHA criterion and was refined by a block diagonal matrix least-squares procedure to final R= 0.084, Moreover, infared spectra, electronic reflection spectra and cyclic voltammetry curve were mearsured.
