η6-bonded naphthalenes. The X-ray structure of [CpFe(octamethylnaphthalene)]PF6 0.5 acetone has been determined. Crystals are monoclinic, the space group C2/c with unit-cell dimensions a = 10.689(4), b = 22.391(5), c = 20.550(4)A, β = 93.41(2)°, Z = 8. The structure determination established a distorted molecular geometry of the octamethylnaphthalene that is different from the free arene and its Cr(CO)3
摘要由[CpFe(o-二氯苯)] +通过光化学配体交换制备了具有4至8个甲基取代基的络合离子[环戊二烯基-Fe(甲基萘)] +。已经确定了η6-键合萘的1H和13C共振的络合位移。已确定[CpFe(八甲基萘)] PF6 0.5丙酮的X射线结构。晶体是单斜晶体,空间单元C2 / c的晶胞尺寸为a = 10.689(4),b = 22.391(5),c = 20.550(4)A,β= 93.41(2)°,Z = 8。结构测定确定了八甲基萘的扭曲分子几何结构,该分子几何结构不同于游离芳烃及其Cr(CO)3络合物。
