Title: Three new extended Preyssler-type polyoxometalates modified by transition metal-2,2 Prime -biimidazole complexes

Abstract

Three extended Preyssler-type ({l_brace}P{sub 5}W{sub 30}{r_brace}) polyoxometalates modified by transition metal (TM)-2,2 Prime -biimidazole (abbreviated as H{sub 2}biim) complexes, namely [Mn(H{sub 2}biim){sub 3}]{sub 5}H{sub 2}[{l_brace}Mn(H{sub 2}biim){sub 2}(H{sub 2}O){r_brace} (NaP{sub 5}W{sub 30}O{sub 110})]{center_dot}39H{sub 2}O (1), [{l_brace}(H{sub 2}biim){sub 2}Zn({mu}-OH)Zn(H{sub 2}biim)({mu}-H{sub 2}biim)Zn(H{sub 2}biim)(H{sub 2}O){r_brace}{sub 2}H{sub 4}(NaP{sub 5}W{sub 30}O{sub 110})]{center_dot}22 H{sub 2}O (2), and {l_brace}(H{sub 4}biim){sub 18}NaH{sub 5}[({mu}-Fe(H{sub 3}biim)(H{sub 2}O){sub 3})({mu}-Fe(H{sub 2}O){sub 4})(NaP{sub 5}W{sub 30}O{sub 110}){sub 2}]{sub 2}{center_dot}78H{sub 2}O{r_brace}{sub n} (3) have been hydrothermally synthesized, and characterized by physicochemical and spectroscopic methods. Their catalytic activities have been investigated. 1 contains mono-supporting {l_brace}P{sub 5}W{sub 30}{r_brace} anions. In compound 2, a {l_brace}P{sub 5}W{sub 30}{r_brace} anion is bi-supported by two symmetrical chains constructed by trinuclear zinc complexes. Compound 3 is composed of infinite 1-D zigzag chains built up of {l_brace}P{sub 5}W{sub 30}{r_brace} polyoxoanions linked via [Fe(H{sub 2}O){sub 4}]{sup 3+} and [Fe(H{sub 3}biim)(H{sub 2}O){sub 3}]{sup 4+} fragments. H{sub 2}biim ligands adopt three coordination modes in the structure. All these compounds have 3-D supramolecular frameworks via extensive hydrogen-bonding interactions. - Graphical abstract: Three new extended Preyssler-type polyoxometalates modified by TM-2,2 Prime -biimidazole complexes are obtained, they display high thermal stabilities.
