Abstract: The title complex was prepared from the reaction of PhSeH, Et3N, AgNO3and Me4NCL IN CH3CN/MeO Hunder a nitrogen atmosphere. The colorless, airsensitive crystal belongs to the monoclinic system with space group P21/c, a=1.7094(3) nm, b=15626(3) nm, c=2.1237(4) nm,β =110.83(3), V=5.3017(17)nm3, Dc=1.940 g/cm3, Z=4. The final Ris 0.0809 for 6938 reflection. The structure of the title complex is built up by Ag4Se6adamatanetype cluster anion and bulky cation. The structure of the title cluster anion [Ag4(SePh)6]2-can be considered as a tetrahedron of silver atoms inscribed in a distorted octahedron of selenium atoms. The silver atoms are in a distorted trigonal planar coordination by three μ2-selenium atoms.

Key words: Tetranuclear silver cluster anion, Selenophenolate, Crystal structure
