The synthesis and characterization of a series of divalent terphenyl transition metal methyl complexes {ArM(mu-Me)}(2) (M = Cr (1), Ar = C6H-2,6-(C6H2-2,4,6-Pr-i(3))(2)-3,5-Pr-i(2), abbreviated as 3,5-Pr-i(2)-Ar*; M = Mn(2), Fe(3),Ar = C6H3-2,6-(C6H2-2,4,6-Pr-i(3))(2), abbreviated as Ar*) as well as a phenyl-bridged iron complex {Ar*Fe(mu-Ph)}(2) (4) are described. Complexes 1-4 were prepared by reaction of the corresponding terphenyl metal halide With LiMe or LiPh and have dimeric structures, in which three-coordinate metals are bridged by methyl or phenyl groups. Each chromium atom in 1 features a further interaction with the ipso-carbon of the flanking aryl ring; while the manganese and iron atoms in 2 and 3 have distorted trigonal-planar geometry. Complexes 1-4 are rare examples of low-coordinate transition metal complexes of methyl or phenyl groups, and they were characterized by X-ray crystallography, NMR, and UV-vis spectroscopy, elemental analysis, and magnetic measurements.
