Abstract

A cyanide-bridged Ni₉Mo₆ cluster (1) capped with chelating bidentate ligands was prepared by self-assembling [Mo(CN)₈]^3-, Ni²⁺, and bipyridine in a stoichiometric ratio. Compound 1 crystallized in the triclinic system with space group P over(1, ̄) shows a body-centered Ni cube capped with six Mo entities. The non-covalent π-π stackings present in 1 lead to the extension of the molecule to a 2D sheet. Magnetic data exhibit that intracluster ferromagnetic interactions in 1 are operative through the CN linkage coupled with zero-field splitting of the cluster with an S = 12 ground state.
