Abstract

Abstract: A giant tetrahedral heterometallic polyoxometalate (POM) [Dy30 Co8 Ge12 W108 O408 (OH)42 (OH2 )30 ] 56−, which shows single‐molecule magnet (SMM) behavior, is described. This hybrid contains the largest number of 4f ions of any polyoxometalate (POM) reported to date and is the first to incorporate two different 3d–4f and 4f coordination cluster assemblies within same POM framework. Abstract : Record SMM POM : A new class of polyoxometalate (POM) containing 3d–4f and 4f aggregates encapsulated by [ A ‐α‐GeW9 O34 ] 10− ligands to give [Dy30 Co8 Ge12 W108 O408 (OH)42 (OH2 )30 ] 56− is described. This hybrid with single‐molecule magnet (SMM) behavior contains the largest number of 4f ions of any POM reported to date and is the first to incorporate two different 3d–4f and 4f coordination cluster assemblies within same POM framework.
