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.
报道了一种基于八氰钨酸盐（Ⅴ）的新型单链磁体{[(Tpm)Co(DMF)W(CN)][Co(DMF)]·2DMF} （Tpm = 1,1,1-三吡唑甲烷），其有效势垒为39.7(3) cm。链状的类伊辛磁各向异性源于Co（Ⅱ）离子近乎平行的局域取向，单轴磁各向异性的来源是八面体环境被三齿封端的Tpm配体扭曲成三角结构。
