Despite the discovery of a series of fullerenes and a handful of noncarbon clusters with the typical topology of Ih-C60, the sm.llest fullerene with a large degree of curvature, C20, and its other-elem.nt counterparts are difficult to isolate experim.ntally. In coinage m.tal nanoclusters（NCs）, the first all-gold fullerene, Au32, was discovered after a long-lasting pursuit, but the isolation of sim.lar silvery fullerene structures is still challenging. Herein, we report a flying saucer-shaped 102-nuclei silver NC（Ag102） with a silvery fullerene kernel of Ag32, which is em.raced by a robust cyclic anionic passivation layer of（KPO4）10. This Ag32kernel can be viewed as a non-centered icosahedron Ag12encaged into a dodecahedron Ag20, form.ng the silvery fullerene of Ag12@Ag20. The anionic layer（KPO4）10is located at the interlayer between the Ag32kernel and Ag70shell, passivating the Ag32silvery fullerene and tem.lating the Ag70shell. The ~tBuPhS-and CF3COO-ligands on the silver shell show a regioselective arrangem.nt with the 60 ~tBuPhS-ligands as expanders covering the upper and lower of the flying saucer and 10 CF3COO-as term.nators neatly encircling the edges of the structure. In addition, Ag102 shows excellent phototherm.l conversion efficiency（η） from.the visible to near-infrared region（η = 67.1% ± 0.9% at 450 nm. 60.9% ± 0.9% at 660 nm.and 50.2% ± 0.5% at 808 nm., rendering it a prom.sing m.terial for phototherm.l converters and potential application in rem.te laser ignition. This work not only captures silver kernels with the topology of the sm.llest fullerene C20, but also provides a pathway for incorporating alkali m.tal（m. into coinage m.tal NCs via m.oxoanions.
