Abstract

The new tungstovanadate (trenH)2(trenH2)2[W4V13O44]· ca.11H2O was prepared under solvothermal conditions in a basic solution at pH ≈ 12. The cluster core contains VIV/VV centers with delocalized spins exhibiting strong antiferromagnetic exchange interactions as evidenced by temperature-dependent magnetic susceptibility measurements pointing to an S = 1/2 magnetic ground state. The structure features an eight-membered ring composed of four alternating edge-sharing VO5 pyramids and VO6 octahedra encapsulating a central Keggin fragment. [ABSTRACT FROM AUTHOR]
