Keggin polyoxometalate with pendant tricyclic, aromatic entity

Abstract: A Keggin polyoxometalate with pendant tricyclic, aromatic entity, formulated as (Hpbpy)5[PW11O39Co(pbpy)]·2H2O (1) (pbpy=5-phenyl-2-(4-pyridinyl)pyridine), was synthesized and characterized by X-ray single crystal structure analysis and temperature-dependent magnetic susceptibility, which represents an unprecedented organic capped-structure. Crystal data: C96H81N12O41PCoW11, triclinic, P-1, a=14.352(3)Å, b=20.467(4)Å, c=21.141(4)Å, α=61.30(3)°, β=75.87(3)°, γ=88.63(3)°, V=5250.5(18)Å3, Z=2. [Copyright &y& Elsevier]
