Tetrakis(μ-2-biphenylcarboxylato-O:O')bis[chlororhenium(III)] Bis(dichloromethane) Solvate

The title complex, [Re₂Cl₂(C₁₃H₉O₂)₄].2CH₂Cl₂, has the well known `paddle-wheel' structure common in many M₂(O₂CR)₄ structures and the Cl ligands occupy the axial positions. The Re atoms are joined by a quadruple bond of length 2.2363 (7) Å and each metal atom is in a pseudo-octahedral environment. The molecule contains an inversion centre and two ortho-phenyl groups of the carboxyl­ate ligands extend out over each axial region.
