Vs. Joshi et al., STEREOCHEMISTRY OF MOLYBDENUM(II) PI-ALLYL COMPLEXES, Proceedings of the Indian Academy of Sciences. Chemical sciences, 108(3), 1996, pp. 217-227
The stereochemistry of molybdenum(II) pi-allyl complexes is generally
governed by intramolecular interactions between the ligand and the all
yl group substituents. Interatomic repulsions are normally dominant. H
owever, weak, attractive interactions may sometimes dictate conformati
onal preferences. Examples include new organomolybdenum complexes cont
aining pyrazole-derived chelating ligands. Structural information has
been obtained from NMR spectroscopy and single crystal X-ray diffracti
on.
