(Et4N)[WIII(DAPBH)(CN)2], the first pentagonal-bipyramidal W(iii) complex with unquenched orbital angular momentum: a novel Ising-type magnetic building block for single-molecule magnets†
Abstract
The first pentagonal-bipyramidal tungsten(III) complex (Et4N)[WIII(DAPBH)(CN)2] with a N3O2-type Schiff-base ligand and two apical cyanide groups was synthesized and characterized structurally and magnetically. The complex has a low-spin (S = 1/2) ground state and features unquenched orbital angular momentum ML = ±1 causing very strong Ising-type magnetic anisotropy.
