Metal π-Complexes of Benzene Derivatives, 36. - The Structure of μ(η6:η6-Biphenyl)bis[(η6-benzene)metal] Complexes in Rigid Solution and in the Crystalline StateFor μ(η6:η6-C6H5C6H5)[η6-C6H6)Cr]2 (2) an antiperiplanar conformation has been established by means of X-ray diffraction. Two (C6H6)Cr units coordinate to planar bridging biphenyl. This configuration differs from that of the diradical dication 2d⊕ d⊕ in rigid solution. According to the zero-field splitting parameter D in the EPR spectrum, 2d⊕ d⊕ adopts a synclinal conformation, the half-sandwich fragments coordinating to twisted biphenyl (dihedral angle α ≍ 60°).
