K. Yamanari et al., SYNTHESIS AND STRUCTURE OF A NOVEL DOUBLY BRIDGED DINUCLEAR COBALT(III) PEROXO COMPLEX [(TREN)CO(MU-O2)(MU-S2O3)CO(TREN)]I2 [TREN = TRIS(2-AMINOETHYL)AMINE], Chemistry Letters, (11), 1993, pp. 1855-1858
A novel (mu-peroxo)(mu-thiosulfato) bridged cobalt(III) complex [(tren
)Co(mu-O2)(mu-S2O3)Co(tren)]2+ [tren = tris(2-aminoethyl)amine] was pr
epared. The complex shows a characteristric UV/VIS absorption spectrum
and the X-ray crystal structure reveals that the complex has an unpre
cedented large Co-O-O-Co torsion angle 75.5(2)-degrees.
