•Two octacyanometallate based chains {WNi} and {MoNi} have been synthesized.•Ferromagnetic interaction dominates in them.•The coupling interaction of WVNiII chain was larger than the MoVNiII chain.
The preparation, single-crystal X-ray crystallography and magnetic properties are reported for two single-zigzag chain complexes {[W(CN)8][Ni(imi)4]}·Bu4N·CH3OH·2H2O (1) and {[Mo(CN)8][Ni(imi)4]}·Bu4N·2H2O (2) (imi = imidazole, Bu = normal-butyl). The structure studies reveal that both complexes feature one-dimension anion chains linked by [W(CN)8]3 − units in 1 or [Mo(CN)8]3 − units in 2. Magnetic studies show that strong ferromagnetic exchange is operative within the WV(μ-CN)NiII units for (1) and MoV(μ-CN)NiII units for (2).
Graphical abstractTwo cyano-bridged based {WNi} and {MoNi} chain have been synthesized by utilizing two octacyanometallate precursors [M(CN)8]3 − (M = Mo, W) with the Ni2 +(imidazole)4 as the second building block. The ferromagnetic interaction dominates in them.Figure optionsDownload full-size imageDownload as PowerPoint slide
