(η6-Xn-substituted-arene)Cr(CO)3
complexes (X = OMe, n = 2, 3)
with
(η6-benzene)Mn(CO)xL3-x
PF6 complexes (L = P(OEt)3, x =
0, 1) gave rise to the formation
of di-, tri-, and tetrapolymetallic complexes depending on the
experimental conditions. A
“one-pot” procedure was developed to obtain tetranuclear complexes
directly from (η6-arene)Cr and -Mn mononuclear complexes. The molecular structures of the
trinuclear complex

have been determined by X-ray crystallography.
