Abstract: The title complex was prepared through the reaction of(PPh3)2Ag(S2CSPr3iC6H2)formed by inserting of CS2 into Ag-S bond of Ag(SPr3iC6H2) in the presence of PPh3 with CH2Cl2-PriOH under mild conditions.The colorless block crystal belongs to the trigonal system with space group R3,a=2.7886(11)nm,c=1.0798(5)nm,V=5.796(4)nm3,Dc=1.2859.cm-3,Z=3.The final Ris 0.060 for 1753 reflections (F>4.0σ(F)).The core of the title compound can be considered as a planar six-membered cycle Ag3S3 of alternating silver and sulfur atoms. In addition,there exists a PriOH molecule in the unit cell.
