Abstract

A new octacyanotungstate(V) based single chain magnet {[(Tpm)Co(DMF)W(CN)₈]₂[Co(DMF)₄]·2DMF}_n (1, Tpm = 1,1,1-trispyrazoylmethane), with an effective barrier of 39.7(3) cm⁻¹ is reported. The Ising-like magnetic anisotropy of the chain originates from the nearly parallel local orientations of the Co(II) ions with the source of the uniaxial magnetic anisotropy being a trigonal distortion of the octahedral environment with the fac-tridentate capping Tpm ligand.
