The homoleptic silver aryl selenolate complex [Ag8(2,4,6-Pr3iC6H2Se) 8] 1 was synthesized by the reaction of AgNO3 with an equivalent amount of 2,4,6-triisopropylbenzeneselenol (2,4,6-Pr3iC6H2SeH) in MeCN in the presence of triethylamine at room temperature for 4 h. Recrystallization by slow diffusion of CH3OH into a CH2Cl2 solution gave yellow block crystals. The crystal structure determination indicates that the structure of the Ag8Se8 core of complex 1 consists of a compressed distorted Ag8 hexagonal bipyramid embedded in a distorted rhombohedron formed by eight selenium atoms of the aryl selenolate ligands. The cluster exhibits a strong optical limiting effect with threshold of 0.2 J cm-2, which is about 2.5 times lower than that of C60 in toluene under identical experimental conditions.
