摘要

标题化合物C40H42Ge4分子的中心Ge-Ge键位于反转中心，产生由四个四面体配位的Ge原子组成的之字形主链。对称独立的Ge-Ge键比其他有机四日耳曼键略短，而Ge-CPh (Ph =苯基)和Ge-CMe (Me =甲基)的距离具有其通常值。在晶体中，存在与Ge4主链方向平行的Ph6Me4Ge4分子(010)层，仅靠范德华力维系在一起。比较了有机取代低聚聚糖的主键长度。

Crystal structure of 2,2,3,3-tetra-methyl-1,1,1,4,4,4-hexa-phenyl-tetra-germane.

The mol-ecule of the title compound, C40H42Ge4, lies with its central Ge-Ge bond on an inversion centre giving rise to a zigzag backbone of four tetra-hedrally coordinated Ge atoms. The symmetrically independent Ge-Ge bonds are slightly shorter than in other organo-tetra-germanes whereas the Ge-CPh (Ph = phen-yl) and Ge-CMe (Me = meth-yl) distances have their usual values. In the crystal, (010) layers of Ph6Me4Ge4 mol-ecules with a parallel orientation of the Ge4 backbone exist, held together by van der Waals forces only. Main bond lengths in organo-substituted oligogermanes are compared.

期刊介绍： Acta Crystallographica Section E: Structure Reports Online is the IUCr highly popular open-access structural journal. It provides a simple and easily accessible publication mechanism for the growing number of inorganic, metal-organic and organic crystal structure determinations. The electronic submission, validation, refereeing and publication facilities of the journal ensure very rapid and high-quality publication, whilst key indicators and validation reports provide measures of structural reliability. In 2009, the journal published over 4000 structures. The average publication time is less than one month.
