tert ‐Butylphosphonic acid and lanthanide precursors were employed to construct two high‐nuclearity hybrid silver(I)–ytterbium(III) phosphonate clusters: compound 1 consists of a Ag 16 ethynide cluster fused with a trinuclear hydroxoytterbium phosphonate cluster, whereas compound 2 is composed of two Ag 16 ethynide clusters bridged by a hexanuclear oxo/hydroxoytterbium phosphonate cluster. Using transition‐metal‐substituted lacunary polyoxotungstates in place of the lanthanide reactant, new phosphonate‐functionalized silver(I)–copper(II) ethynide clusters [Ag 34 Cu 6 ( 3 ) and Ag 37 Cu 6 ( 4 )] and silver(I) ethynide clusters [Ag 51 ( 5 ) and Ag 72 ( 6 )] were obtained. The structures of complexes 3 – 6 feature core–shell arrangements, in which silver(I)–copper(II) or silver(I) ethynide cluster shells stabilized by peripheral phosphonate ligands enclose different kinds of tungstate core templates.
