Synthesis and X-ray structures of octanuclear silver(I) cluster [Ag8(μ6-S){S2P(OC2H5)2}6] and its copper(I) analogue [Cu8(μ8-S){S2P(OC2H5)2}6]

Abstract The octanuclear cluster of silver(I) [Ag 8 (μ 6 -S){S 2 P(OC 2 H 5 ) 2 } 6 ] comprises eight Ag atoms located at the corners of a cube elongated along the threefold axis with a μ 6 -S atom in its center and each sulfur atom of the S 2 P(OC 2 H 5 ) 2  − ligand bridges two opposite sides of a cubic face formed by four Ag atoms. An infinite arrangement of {[Ag 8 (μ 6 -S){S 2 P(OC 2 H 5 ) 2 } 6 ]·H 2 O} ∞ is formed along the c -axis.
