簇合物[（η^5-C5Me5）WS3{Cu（PPh3））3Cl]（PF6）的合成及晶体结构

Synthesis and Crystal Structure of an Organometallic Tetranuclear Cationic Cluster [（η^5-C5Me5）WS3{Cu（PPh3））3Cl]（PF6）

Reaction of a preformed cluster [｛(η5-C5Me5)WS3｝3Cu7(MeCN)9](PF6)4 (1) in MeCN with LiCl and PPh3 gave rise to a tetranuclear cationic cluster [(η5-C5Me5)WS3｛Cu(PPh3)｝3Cl](PF6) (2). The title compound 2 was char- acterized by elementary analysis, IR, UV-Vis, 1H NMR, and its crystal structure was determined by X-ray single crystal diffraction. It belongs to monoclinic, space group P21/c with a=1.7998(4) nm, b=2.0836(4) nm, c=1.9135(4) nm, β=113.63(3)°, V=6.574(3) nm3, Z=4. The cluster cation [(η5-C5Me5)WS3｛Cu(PPh3)｝3Cl]+ of 2 contains a strongly distorted, cubane-like structure [WS3Cu3Cl] in which one Cl weakly fills into the void of the nido-like [WS3Cu3] fragment with three relatively long Cu-Cl distances. CCDC: 270415.
