Abstract: Two polyanions [Se <superscript>I V</superscript> <subscript>2</subscript> Pd <superscript>II</superscript> <subscript>4</subscript> W <superscript>VI</superscript> <subscript>14</subscript> O <subscript>56</subscript> H] <superscript>11-</superscript> and [Se <superscript>I V</superscript> <subscript>4</subscript> Pd <superscript>II</superscript> <subscript>4</subscript> W <superscript>VI</superscript> <subscript>28</subscript> O <subscript>108</subscript> H <subscript>12</subscript> ] <superscript>12-</superscript> are the first hybrid polyoxometalates in which classical (Group 5/6 metal based) and non-classical (late transition-metal based) polyoxometalate units are joined. Requiring no supporting groups, this co-condensation of polyoxotungstate and isopolyoxopalladate constituents also provides a logical link between POM-Pd <superscript>II</superscript> coordination complexes and the young subclass of polyoxopalladates. Solid-state, solution, and gas-phase studies suggest interesting specific reactivities for these hybrids and point to several potential derivatives and functionalization strategies.<br /> (© 2016 Wiley-VCH Verlag GmbH & Co.
