Synthesis and Crystal Structure of a Decanuclear Silver（I）-thiolate Compound Ag10S[S2P（OEt）2]8

Synthesis and crystal structure of a decanuclear silver(I)‐thiolate compound Ag10S[S2P(OEt)2]8

A new decanuclear silver(I) compound Ag₁₀(μ₈‐S)(dtp)₈ dtp=S₂P(OEt)₂] was isolated from a reaction mixture containing W₂S₄(dtp)₂ and AgN0₃, and its solid‐state molecular structure was determinated by X‐ray crystallography. The crystallographic study revealed that the compound contains a distorted mono‐capped quasi‐prism Ag_io] with an octat‐bridging S atom at the center of the prism. The compound (C₃₂H₈₀Ag₁₀O₁₆P₈S₁₇, M_r=2592.46) crystallizes in the monoclinic P2₁/n space group, with a = 1.5111(5) nm, b=2.3656(8) nm, c=2.284(1) nm, β= 96.88(3)°, V=8.107(5) nm³, Z=4 and D,=2.12 g · cm^?3. The solution using direct method and full‐matrix least‐squares refinement led to R=0.066, Rw=0.078 for 3928 reflections with I3σ(I).
