A series of new polyoxometalate-based metal–organic complexes with different rigid pyridyl-bis(triazole) ligands: assembly, structures and electrochemical properties

Abstract

Two novel Anderson-type and three octamolybdate (γ-Mo8O26) polyoxometalate-based metal–organic complexes were synthesized and structurally characterized. The electrochemical and bifunctional electrocatalytic behaviors of the title compounds have been investigated in detail.

Cobalt complexes tuned by Anderson-type polyoxometalates and bis-amide derivative ligands featuring a ‘V’-like connector for efficient ampere sensing and the visible-light catalytic reduction of Cr(vi)

“…22,23 Furthermore, the types of POMs have shown great effects on the structures of POM-based complexes. For example, in the structures of {[Zn II 5 (trz) 6 (H 2 O) 12 ][α-B-AlMo 6 (OH) 6 O 18 ] 2 }·(α-B-HAlMo 6 (OH) 6 O 18 )·23H 2 O and {[Cu II 3 (tybm) 3 (H 2 O) 4 ][α-A-TeMo 6 O 24 ]} 2 ·(α-A-H 6 TeMo 6 O 24 )·16H 2 O reported by Tian et al , 24 H{Co 2 (Hpyttz-I) 2 (H 2 O) 6 [CrMo 6 (OH) 6 O 18 ]}·8H 2 O and {Co 2 (H 2 pyttz-I) 2 (H 2 O) 4 [TeMo 6 O 24 ]}[Co(H 2 O) 6 ]·3H 2 O prepared by our group, 25 the use of different Anderson-type POMs had an important influence on the final structures of the target complexes.…”

1,2,4-Triazole Derivatives in Medicine and Pharmacy and Application Prospects

“…Figure 18. The structure of diamino-1,2,4-triazole complex with complex ion Cu (II) [20] Continuing the study of complex compounds [21], the authors investigated new Anderson-type polyoxometalates and organometallic complexes based on octamolybdates with triazole ligands. The basis for the creation of complexes included a combination with Co (II).…”

Three new POM-based coordination polymers with 1,3,5-tris(1-imidazolyl)benzene ligand: syntheses, structures and proton conductivity

“…Among the many organic ligands, nitrogen-containing heterocyclic ligands arouse great interest owing to predominant coordination ability and abundant coordination modes. [13][14][15][16][17] In the past, various organic ligands have been investigated to assemble hybrid architectures, such as 1,4-bis(1-imidazolyl)benzene, 1,4-bis(benzimidazol-1-yl) benzene and 1,3-bis(1-imidazolyl)benzene. [18][19][20] Recently, our group has also systematically investigated 2,6-bis(1,2,4-triazol-1yl)pyridine, 21 2,6-bis(1-imidazolyl)pyridine, 22, 23 1,3-bis(4H-1,2,4triazol-4-yl)benzene, 24 etc.…”
