Enforcing Ising-like magnetic anisotropy via trigonal distortion in the design of a W(v)–Co(ii) cyanide single-chain magnet

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...

Descripción
Sumario: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.
