چکیده انگلیسی


• The polyanion represents the first example of sandwich-type POM modified with aminopyrazine ligand.
• The existence of weak antiferromagnetic coupling in trinuclear Ni(II) clusters
• The anion crystallized with dinuclear nickel complex constructed from an aminopyrazine bridging two [Ni(H2O)5]2 + ions as part of counterions.

A new organic–inorganic hybrid tungstoantimonate, Na4[Ni2(apy)(H2O)10]1/2[(Ni(Hapy))3(Na(H2O)2)3(SbW9O33)2]·23H2O (1) (apy = aminopyrazine), has been synthesized and fully characterized. Single crystal X-ray diffraction analysis indicates that the polyanion [(Ni(Hapy))3(Na(H2O)2)3(SbW9O33)2]6 − displays a sandwich-type dimeric structure in which the Ni2 + ions in the central belt are modified by aminopyrazine ligands. The contrast experiment analyses show that the existence of organic amine ligand is a key role to the formation of the stable Hervé-type tungstoantimonate containing trinuclear nickel(II) ions, which crystallized with dinuclear nickel complex constructed from an aminopyrazine bridging two [Ni(H2O)5]2 + ions as part of counterions. The variable-temperature magnetic measurements of 1 exhibit the weak antiferromagnetic exchange interactions among Ni(II) clusters in 1.

A new Hervé-type tungstoantimonate containing trinuclear nickel ions modified with aminopyrazine ligand to substitute coordinated water molecules attached to nickel ions has been synthesized and fully characterized.Figure optionsDownload as PowerPoint slide
