Molecular assembly and micellization of molybdenum(V, IV) thiolate and selenolate complexes with long hydrocarbon chains

Molybdenum(IV, V) thiolate and selenolate complex with four long bundling h ydrocarbon chains connected to the amide group, (Ph4P)[(MoO)-O-V{S-2-CH3(CH 2)(10)CONHC6H4}(4)] and (NEt4)(2)[(MoO)-O-IV{Se-2-CH3(CH2)(10)CONHC6H4}(4)] were synthesized. The four chains are oriented toward the same direction i n the solution as established by H-1 NMR. These complexes were soluble in a n aqueous micellar solution and stabilized against hydrolysis in such aqueo us media efficiently by the hydrocarbon chains. The preliminary results of X-ray analysis revealed the individual molecular assembly behavior which de pends significantly on the oxidation slate of metal ion and the kind of coo rdinated atom.
