Synthesis and structure of lipophilic dioxo-molybdenum (VI) bis(hydroxamato) complexes

New methods for the synthesis of complexes of molybdenyl with hydrophobic alkyl-substituted hydroxamic acids have been developed. A number of novel coordination compounds of the general formula MoO2L2 (where HL is decano-, N-methyl-decano-, N-methyl-hexano-, N-methyl-1-adamantano- and N-tert-butyl-hexanohydroxamic acids) have been synthesized. All compounds obtained have been characterized by IR, 1H NMR spectroscopy and X-ray crystallography. The effect of the electron donating and steric properties of ligand substituents on the structure of complexes is discussed.
