Abstract

The first paramagnetic pentagonal-bipyramidal complex of Mo(III) with a N₃O₂-type Schiff-base ligand was synthesized by the comproportionation reaction between Mo(II) and Mo(IV) congeners. The complex has a low-spin (S = 1/2) ground state of Mo^III(4d³) with double orbital degeneracy and unquenched orbital momentum, which result in strong Ising-type magnetic anisotropy.
