A new enneanuclear nickel(II) cluster with a rectangular face-centered trigonal prism structure and cluster glass behavior

An enneanuclear nickel(II) complex with a rectangular face-centered trigonal prism structure bridged by μ2-pyrazolate, μ6-CO32− and μ3-OH−groups was synthesized. It displays cluster glass-like magnetic behavior assigned to the single molecule magnet properties of {Ni9} clusters and weak intercluster interaction.
