orthorhombic, space group Pbca, Z= 8 in a unit cell of dimensions a= 16.513(10), b= 28.536(30), and c= 15.429(8)Å. This complex Is also the major product in the reaction of [Pt(C2H4)3] with hfb in the presence of cod. A minor product in this reaction, [[graphic omitted](CF3)}(cod)2], is formed in high yleld on treatment of [[graphic omitted](cod)2] with hfb. A crystal-structure determination has established
[Pt(cod)2 ](cod = 1,5-C 8 H 12)与六氟丁-2-炔(hfb)的反应得到[[图中未示出](CF 3)}(cod)],其与三苯基膦反应,一氧化碳或六氟丁-2-炔基,以提供[[未图示](CF 3)}(PPh 3)2 ],[[未图示](CF 3)}(CO)2(cod)]和[ [图省略](CF 3)}(cod)2 ]包含三元,四元,六元和八元环。雷公藤属物种已通过X射线晶体学在结构上进行了鉴定。晶体是正交晶体,空间群Pbca,在尺寸为a = 16.513(10),b = 28.536(30)和c = 15.429(8)Å的晶胞中Z = 8 。这种复合物也是[pt(C 2 H 4)3 ]与hfb在鳕鱼存在下反应的主要产物。在用hfb处理[[未图示](cod)2 ]时,以高收率形成该反应中的次要产物[[未图示](CF 3)}(cod)2。晶体结构的确定已经确定了在该分子中存在
