A new octacyanotungstate(v) based single chain magnet {[(Tpm)Co(DMF)W(CN)][Co(DMF)]·2DMF} (, Tpm = 1,1,1-trispyrazoylmethane), with an effective barrier of 39.7(3) cm 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 -tridentate capping Tpm ligand.
