Zusammenfassung
Trends in solid-state structures were used to identify preferred intramolecular movements in half-sandwich compounds [CpFe(CO){C(=O)R}PPh3]. Three weak interactions were analyzed: 1)the CH/ donor-acceptor interaction of phenyl rings in the PPh3 ligand, 2)the Ph-PPh3 face-on Cp stabilization, and 3)the hydrogen bond between the oxygen atom of the acyl group and an ortho-C-H bond of one of the PPh3 ...

Clockwise and counter-clockwise rotations established directed and coupled movements of the PPh3 ligand, the acyl group, and the phenyl rings within the PPh3 ligand.
