Figure 2

Molecular structures of the intermediates 6 a (left), 6 b (middle) and 6 c (right). Anisotropic displacement is set to the 50 % probability level. Only the anionic part is shown. The cations and the crown ethers are omitted, and Cp as well as CO substituents are drawn translucent for clarity. Selected bond lengths [Å] and angles [°]: 6 a: P−Mo1/P−Mo1′ 2.4304(6), P−Si1/P−Si1′ 2.2574(8), Mo1‐Mo1′ 3.1889(5), Si1‐P−Si1′ 103.85(5); 6 b: As−Mo1 2.5213(3), As−Mo2 2.5128(3), As−Si1 2.3410(8), As−Si2 2.3540(8), Mo1‐Mo2 3.2445(3), Si1‐As−Si2 104.39(3); 6 c: Sb−Mo1 2.6887(8), Sb−Mo2 2.6907(7), Sb−Si1 2.561(2), Sb−Si2 2.559(2), Mo1‐Mo2 3.2597(8), Si1‐Sb−Si2 105.27(7).
