    摘要:
    The azacyclopentadienyl compounds (2,5-C4tBu2RHN)MCl3 (M = Ti, Zr, Hf; R = H, SiMe3) have been prepared as stable solids from the lithiated pyrroles and MCl4. The pi-coordination of the azacyclopentadienyl ligands, as suggested from C-13 NMR data, has been confirmed for (2,5-C4tBu2H2N)TiCl3 by an X-ray diffraction study.

    摘要:
    2,5-二(叔丁基)吡咯 (1) 锂化生成双 (四氢呋喃) 锂 2,5-二(叔丁基) 吡咯烷 (2),它在溶液和固态中都是单体. 由于锂原子的配位数为 3,观察到短的 Li-O 和 Li-N 键长为 193 pm。2与三(三甲基甲硅烷基)-甲基氯化锌(3)的复分解反应得到无色双[三(三甲基-甲硅烷基)甲基锌]氯化物2,5-二(叔丁基)吡咯化物(4)。吡咯配体和氯原子桥接锌原子。一个锌原子与吡咯化物取代基的氮原子键合,而另一个与相反的 C-C 键键合。在 215 pm,与烷基锌酰胺中的相比,Zn-N 键非常长,而 Zn-C 距离位于锌和 η5 键合的环戊二烯配体之间的 Zn-C 键长范围内。1 和低熔点 THF 加合物 1·thf 的分子结构显示出类似的 2,5-二(叔丁基)吡咯分子,但在后一种情况下观察到弱 N-H···O 键( N–H 97 pm,O……H 199 pm)。

    The present invention is related to a family of liquid group 4 precursors represented by the formula: (pyr*)M(OR1)(OR2)(OR3) wherein pyr* is an alkyl substituted pyrrolyl, wherein M is group 4 metals include Ti, Zr, and Hf; wherein R1-3 can be same or different and selected from group consisting of linear or branched C1-6 alkyls; preferably C1-3 alkyls; R4 is selected from the group consisting of C1-6 alkyls, preferably branched C3-5 alkyls substituted at 2, 5 positions to prevent the pyrrolyl coordinated to the metal center in η1 fashion; n=2, 3, 4. Most preferably the invention is directed to (2,5-di-tert-butylpyrrolyl)(tris(ethoxy)titanium, (2,5-di-tert-amylpyrrolyl)(tris(ethoxy)titanium, and (2,5-di-tert-amylpyrrolyl)(tris(iso-propoxy)titanium. The invention is also directed to (cyclopentadienyl)(2,5-di-methylpyrrolyl)(bis(ethoxy))titanium. Deposition methods using these compounds are also contemplated.
    本发明涉及一类液态4族前体化合物,其化学式为:(pyr*)M(OR1)(OR2)(OR3),其中pyr*是一种取代烷基的吡咯烷基,M代表4族金属,包括钛、锆和铪;R1-3可以相同或不同,并从由线性或支链C1-6烷基组成的群体中选择;最好选择C1-3烷基;R4从由C1-6烷基组成的群体中选择,最好选择支链C3-5烷基,其在2,5位置被取代以防止吡咯烷基以η1方式配位到金属中心;n = 2、3、4。最好的实施例是(2,5-二叔丁基吡咯烷基)(三乙氧基钛)、(2,5-二叔戊基吡咯烷基)(三乙氧基钛)和(2,5-二叔戊基吡咯烷基)(三异丙氧基钛)。本发明还涉及(环戊二烯基)(2,5-二甲基吡咯烷基)(双乙氧基)钛。本发明还考虑了使用这些化合物的沉积方法。

    Tetra-tert-butyl-diazanickelocene has been synthesized from NiCl2 and Li(C4H2tBu2N) and its crystal structure determined. Small, albeit significant structural differences in the diazaferrocene, -cobaltocene, -nickelocene series are explained in terms of the sequential filling of π-antibonding levels.

    显示二氮杂二茂铁的电子结构与二茂铁相似,在前者中没有发现构象偏好的证据。与取代的二茂铁类似物相比,在四叔丁基取代的二氮杂二茂铁中观察到的较小的环旋转障碍归因于杂环系统中更容易的畸变模式。由NiCl 2和Li(C 4 H 2 t Bu 2N)及其晶体结构确定。尽管二氮杂二茂铁,-钴茂金属,-镍茂金属系列的结构差异很小,但仍通过顺序填充π-反键水平进行了解释。在弯曲的主族中,重氮杂环丁烷或-铅茂金属的电子状态不同于常规茂金属的电子状态引起构象偏好,两个氮都指向氮杂-Cp环平面的最大打开方向。
