cis-[M(C6F5)2(THF)2] (M = Pd, Pt; THF = tetrahydrofuran) with PhCCPh has given the novel bis-acetylene-palladium(II) and -platinum(II) complexes cis-[M(C6F5)2(PhCCPh)2]; these are stable even though there seems to be no significant π-back bonding according to the X-ray structure of the platinum complex.
用PhCCPh处理顺式-[M(C 6 F 5)2(THF)2 ](M = Pd,Pt; THF =
四氢呋喃),得到了新颖的双
乙炔钯(II)和-
铂(II) )配合物顺式-[M(C 6 F 5)2(PhCCPh)2 ];即使根据
铂络合物的X射线结构似乎没有明显的π背键,它们也很稳定。
