Abstract

The title compound 3 has been synthesized along the hydride route by treatment of the solvent complex (η⁵‐C₅Me₅)Mn(CO)₂(THF) (THF = tetrahydrofuran) with monogermane, GeH₄, in the presence of sulfuric acid. A single‐crystal X‐Ray structural analysis revealed two conformers of 3 being present in the solid state in a 1:1 ratio (C2/c, monoclinic). Pairs of carbonyl groups almost eclipse each other, while the remaining two CO ligands an exhibit an anti‐conformation relative to the strictly linear MnGeMn framework. Both enantiomeric conformers are geometrically related by a 180°‐rotation of a (C₅Me₅)Mn(CO)₂ fragment around the Mn, Ge, Mn vector. The manganese — germanium bond lenghts average 2.18(2) Å and thus correspond to considerable multiple bonding between these atoms.
