| 14 | Studies on solid state reactions of coordination compounds显示文摘A series of tetranuclear Mo(W)-Ag mixed-metal clusters have been synthesized by makinguse of the solid state reactions of[NH4]2[MYS3](M=Mo,W;Y=O,S),AgX(X=Cl,Br,I)and(n-Bu)4NX’(X’=Cl,Br),two of which[(n-Bu)4N]3[MoOS3Ag3Br4](1)and[(n-Bu)4N]3[WS4Ag3Cl4](2)have been structurally characterized by X-ray analysis.The crystal data:1,cubic,P 3m,a=12.093(4) ,Z=1,R=0.076;2,cubic,P 3m,a=12.059(2) ,Z=1,R=0.075.The clusteranion core[Ag3MS3X’]of the two compounds can be viewed as a cube in which the four metal atomsand the four non-metal atoms are statistically distributed,respectively.Substitution reaction withPPh3 ligand is also discussed for this type of tetranuclear clusters. | LⅩⅢ.Solid state synthesis of a series of tetranuclear Mo(W)-Ag mixed-metal clusters.Crystal structures of | 1993 | Chinese Journal of Chemistry1993，11，5： | 1 |
