is suggested in the solid state. Reaction of AgSbF6 with L1 and PPh3 or PMe2Ph afforded complexes in which the silver is coordinated by a phosphine and an endodentate η3-L1. Similar studies with CuI and HgII showed a reduced tendency for thioether coordination reflected in a reduced denticity of L1. Studies with a range of dithiacycloalkynes and a tetrathiacyclodiyne show that Ag+ and Cu+ can be successfully
通过噻环炔与Ag I,Cu I和Hg II阳离子和阳离子MPR 3(M = Ag,Cu,Hg)片段的反应,制备了一系列配合物。1 H NMR研究表明,1,4,7-trithiacycloundec-9-yne(L 1)与Ag I的配位导致
