Abstract

The bimetallic complex [cis-(CO)4{(MeO)3P}Mn{μ-η16-C6H5C(O)}Cr(CO)3] (1) was obtained by the reaction of [(η6-C6H5Li)Cr(CO)3] with Mn(CO)5Br in the presence of one equivalent of P(OMe)3 at low temperature. The structure of 1, determined by single crystal X-ray diffraction methods, shows the coordination around the manganese atom to be approximately octahedral, with the manganese moiety displaced from the plane of the η6-arene ring away from the Cr(CO)3 group. The phosphite ligand is located on the same side of the molecule as the chromium tripodal moiety, and interlocked between carbonyl ligands. Crystals of 1 are triclinic, space group P1, with Z=2 in a unit cell of dimensions a=8.658(1), b=10.300(1), c=11.891(1) Å, α=90.75(1), β=95.29(1) and γ=95.16(1)°. The structure was refined to Rw=0.029 for 290 parameters using 5112 observed reflections.
