Zusammenfassung:	A 90-nucleus silver cluster ( SD/Ag38 ) cocapped by t BuC 6 H 4 S − and PhCOO − ligands was synthesized using hetero-anion template method. Single-crystal X-ray diffraction (SCXRD) revealed a 90-nucleus metallic dumbbell-like core constructed by two large W 5 O 19 @Ag 38 heads sandwiching one slender (SO 4 ) 2 @Ag 14 waist. Both W 5 O 19 8− and SO 4 2− templates were in situ generated and synergistically induced the formation of the largest known anion-templated silver cluster. Although SD/Ag38 is emission-silent at room temperature, increasingly brighter near-infrared (NIR) emission at ca. 742 nm was detected on cooling from 293 to 93 K. A giant 90-nucleus silver cluster templated by hetero-anions was isolated and characterized.
