The synthesis and characterization of two novel octanuclear mixed-metal clusters: [CrM3O4(O2CEt)8]2Na2(M
Mo,W)
Abstract
Two novel insoluble octanuclear mixed-metal clusters with a centrosymmetric [M3O4CrCrO4M3]14+(MMo,W) core have been synthesized and characterized; a strong absorption near zero magnetic field in the EPR spectrum of the CrW3 cluster is unexpectedly observed.
