Reactivity of organometallic molybdate toward lanthanide cations. Synthesis and structure of polynuclear lanthanide-molybdate complexes

摘要

Novel polynuclear rare earth compounds [La-3(OH2)(7)-(Cp*MoO3)(2)(NO3)(7)] and [La-3(OH2)(5)(THF)(Cp*MoO3)(2)-(NO3)(6)](2)(NO3)(2) were synthesized by reacting [(n-C4H9)(4)N][CP*MoO3] With La(NO3)(3). 6H(2)O in THF. X-ray crystal structural analyses revealed that both these compounds are composed of a La3Mo2O6 unit in which the metal atoms arrange themselves into a trigonal bipyramid. The Ce analogues were also obtained. [GRAPHICS] [References: 8]
