With tuning the ligands from bte, btp, btb to bth, four new decavanadate-based metal–organic hybrid compounds, [Zn(bte)(H{sub 2}O){sub 4}][Zn{sub 2}(bte)(H{sub 2}O){sub 10}](V{sub 10}O{sub 28})·8H{sub 2}O, [Zn{sub 2}(btp){sub 4}(H{sub 2}O){sub 6}](H{sub 2}V{sub 10}O{sub 28})·4H{sub 2}O, [Zn(H{sub 2}O){sub 6}][Zn{sub 2}(btb){sub 2}V{sub 10}O{sub 28}(H{sub 2}O){sub 6}]·4H{sub 2}O, and [Zn{sub 2}(bth)(H{sub 2}O){sub 10}](H{sub 2}V{sub 10}O{sub 28})·6H{sub 2}O (bte=1,2-bis(1,2,4-triazol-1-yl)ethane, btp=1,3-bis(1,2,4-triazol-1-y1)propane, btb=1,4-bis(1,2,4-triazol-1-y1)butane, bth=1,6-bis(1,2,4-triazol-1-y1)hexane), have been synthesized under conventional conditions. The four compounds represent the first examples of decavanadate-based metal–organic hybrids constructed by Zn–bis(triazole) complexes. Their structural analyses show that the four compounds possess different Zn–bis(triazole) structural motifs and various finally structures, which verifies that regular changing the spacers of ligands is an effective strategy to tuning the structures of polyoxometalate-based hybrids. Also, the electrochemical studies show that the compounds have good electrocatalytic activities towards oxidation of nitrite molecules ascribed to V-centers. - Graphical abstract: Four compounds representing the first examples of V{sub 10}O{sub 28}-based hybrids constructed by Zn–bis(triazole) complexes have been synthesized by changing the spacers of the ligands and their electrocatalytic properties have been investigated. - Highlights: • The first examples of V{sub 10}O{sub 28}-based hybrids constructed by Zn-bis(triazole) complexes. • Verifying that changing the spacers of ligands is a strategy to tuning structures. • Showing good electrocatalytic activities toward oxidation of nitrite molecules.
