Abstract

Four new compounds of reduced polyoxomolybdenum phosphate (V) with the formula (H2enMe)4(MnH2O)2{Mn[Mo6O12(OH)3(HPO4)2(PO4)2]2}·5H2O (1) (enMe = 1,2-diaminopropane), (H3N(CH2)4NH3)4(MnH2O)2{Mn[Mo6O12(OH)3(HPO4)2 (PO4)2]2}·2H2O (2), (H3dien)4{Mn[Mo6O12(OH)3(HPO4)2(PO4)2]2}·8H2O (3) (dien = diethylenetriamine) and (H2en)5{Cu2[Mo6O12(OH)3(HPO4)3(PO4)]2}·3H2O (4) (en = ethylenediamine) have been successfully synthesized under similar reactive condition and characterized by single-crystal X-ray diffraction. For compounds 1–3, despite slight distinction of amine, the organic amine template effect lead them to have different topological structures. The transition metal ion Mn2+ was replaced by Cu+, resulting in compound 4 with infinite chains since Cu+ exhibits a two-coordination mode. To the best of our knowledge, compound 4 is the first zigzag chain-like structure reduced polyoxomolybdenum phosphates containing Cu+. Other characterizations of these compounds by elemental, IR, thermal analysis and catalytic properties are also performed. The formation of these four compounds reveals that the organoamine and transition metal play important roles during the synthesis.
