报道了双（１－正戊基环己基茂）二氯化钛［（η５－Ｃ５Ｈ４Ｃ（ＣＨ２）５（Ｃ５Ｈ１１－ｎ］２ＴｉＣｌ２（Ｉ）及双（１－甲基－１－（α－噻吩基）乙基环戊二烯基）二氯化钛［η￣５－Ｃ５Ｈ４Ｃ（ＣＨ３）＿２－］２ＴｉＣｌ２（Ⅱ）的晶体结构和分子结构。二者均系单斜晶系，（Ｉ）的空间群为Ｐ２／ｎ，晶胞参数ａ＝１４．１８０（２），ｂ＝６．５６２（１），ｃ＝１７．０４６（３），β＝９９．６３（１）°，Ｚ＝２，Ｖ＝１５６３．８，Ｄｘ＝１．１８８ｇ／ｃｍ３，Ｆ（０００）＝５９６，Ｍｒ＝５５３．５６，λ＝０．７１０７３μ＝４．５９ｃｍ－１，Ｒ＝０．０５８，Ｒｗ＝０．０６６；（１）的空间群为Ｃ２／ｃ，晶胞参数ａ＝２５．７１３（１），ｂ＝６．６１７（１），ｃ＝１３．５９１（１），β＝９２．７８（２）°，Ｚ＝４，Ｖ＝２３０９．８，Ｄｘ＝１．４３０ｇ／ｃｍ３，Ｍｒ＝４９７．４１，λ＝０．７１０７３，μ＝７．８２２ｃｍ－１，Ｆ（０００）＝１０３２，Ｒ＝０．０５５，Ｒｗ＝０．０７２。茂环上取代基对茂环金属化合物的结构产生较大影响，空间阻碍的增大使得取代基与茂环相连Ｃ－Ｃ单键增长。
Reported the synthesis of titanium (II) complexes of bis (1-n-pentylcyclohexyl) titanium dichloride [(η5-C5H4C (CH2) 5 (C5H11-n] ) Ethylcyclopentadienyl) titanium dichloride [η¯5-C5H4C (CH3) _2-] 2TiCl2 (Ⅱ), both of which are monoclinic, the space of (I) Group is P2 / n, cell parameters a = 14.180 (2), b = 6.562 (1), c = 17.046 (3), β = 99.63 (1) °, Z = V = 1563.8, Dx = 1.188g / cm3, F (000) = 596, Mr = 553.56, λ = 0.71073μ = 4.59cm-1, R = 0.058, Rw = ; (1) The space group is C2 / c, the unit cell parameters a = 25.713 (1), b = 6.617 (1), c = 13.591 (1), β = 92. 78 (2) °, Z = 4, V = 2309.8, Dx = 1.430 g / cm3, Mr = 497.41, λ = 0.71073, μ = 7.822 cm -1, F (000) = 1032 , R = 0.055, Rw = 0.072. The substituents on the epicyclic ring have a great influence on the structure of the metallocene compounds. The increase of the steric hindrance leads to the increase of C-C single bonds between the substituents and the ring.
