SYNTHESIS AND PROPERTIES OF 1,3-((ETA(5)-C6H6)MN(CO)(3))(2)-C5H4 AND 1,4-((ETA(5)-C6H6)MN(CO)(3))(2)-C5H4 - MOLECULAR-STRUCTURE OF [(MU-ETA(5)ETA(5)ETA(5)-C17H15)(CH3)MN2W(CO)(9)]

(exo-C5H5-eta(5)-C6H6)Mn(CO)(3) (2) reacts with (C6H6)Mn(CO)(3+) to yi eld 1,3- and 1,4-{(eta(5)-C6H6)Mn(CO)(3)}(2)-C5H4)] (3). 3 reacts with Fe-2(CO)(9) to yield [(mu-eta(5): eta(5): eta(5)-C17H15)Mn2Fe(CO)(8)] (2). 3 reacts with (n)BuLi to produce a lithiated compound, which reac ts with M(CO)(5)Br (M = Mn, Re), M(CO)(3)(CH3CN)(3) (M = Cr, Mo, W), a nd FeCl3 to yield the corresponding organometallic compounds. The mole cular structure of [(mu-eta(5): eta(5): eta(5)-C17H15)(CH3)Mn2W(Co)(9) ] (6(W)) (space group P2(1)/c; unit cell parameters a = 11.208(6), b = 19.431(3), c = 12.562(2) Angstrom , beta = 91.69 (3)degrees; R = 0.05 2%, R(W) = 0.067%) has been determined.
