The 'wing-bridged' butterfly clusters Fe3CoPdC(Co)(12)(pi-C3H5) 2 and
Fe3CoPdC(CO)(12)(pi(3)-beta-C10H15) 3 have been synthesized; the cryst
al structure of 2 has been determined, and the absorption and circular
dichroism spectra of 3 were investigated and compared with those for
the [Pd(pi(3)-beta-C10H15)Cl](2) chiral complex 4.
