Mo-O-oxo bond distances [mean 1.698(6)Angstrom] correspond to double bonds, Mo-O-oxy [mean 1.951(2)Angstrom] to single bonds, and Mo-N bonds [mean 2,326(3)Angstrom] are lengthened as a result of the effect of the oxo ligands, which are trans to the N atoms.}, keywords = {ATOM TRANSFER-REACTIONS}, isbn = {0108-2701}, url = {://000073458300013}, author = {Ehlert, M.
