Polynucleating oxygen donor ligands as precursors have been employed to construct three high-nuclearity heterometallic ethynide clusters. Compound 2 consists of a Cl@Ag ethynide cluster capped by two trinuclear organooxotin phosphonate clusters [(BuSn)(μ-O)(BuPO)(OMe)(OH)]. Compound 3 consists of a Ag ethynide cluster fused with a nonanuclear oxo-bismuth phosphonate cluster [BiO(BuPO)(BuPOH)], while compound 4 is composed of two Cl@Ag ethynide clusters bridged by a hexanuclear oxo/hydroxo-bismuth phosphonate cluster [BiO(OH)(BuPO)(hfac)(CFCOO)].
多齿氧供体配体作为前体被用于构建三个多核异金属乙炔化物簇。化合物 2 由一个 Cl@Ag 乙炔化物簇被两个三核有机锡膦酸酯簇 [(BuSn)(μ-O)(BuPO)(OMe)(OH)] 封端。化合物 3 由一个 Ag 乙炔化物簇与一个九核氧双膦酸酯簇 [BiO(BuPO)(BuPOH)] 融合而成，而化合物 4 则由两个 Cl@Ag 乙炔化物簇通过一个六核氧/羟基金属膦酸酯簇 [BiO(OH)(BuPO)(hfac)(CFCOO)] 桥联而成。
