TLDR
In this article, the configurational behavior of cyclotetragermanes is described and the crystal structure of [t-Bu(Cl)Ge]4 was established by X-ray diffraction.
Abstract
Condensations of R(Ph)GeCl2 (R = t-Bu and R = CEt2Me) with Mg/MgBr2 in THF produced cyclotetragermanes [R(Ph)Ge]4, which were converted to [R(Cl)Ge]4 by treatment with HCl/AlCl3 or with CF3SO3H followed by CH3COCl. The crystal structure of [t-Bu(Cl)Ge]4 was established by X-ray diffraction. Unusual configurational behavior of cyclotetragermanes is also described.

Strained‐Ring and Double‐Bond Systems Consisting of the Group 14 Elements Si, Ge, and Sn

TL;DR: In this article, a review of the organometallic chemistry of the Group 14 elements E = Si, Ge, Sn in the 1980's is highlighted by the successful construction and characterization of three systems previously thought to be too reactive to exist: (1) three-membered ring compounds including cyclotrisilane, cyclotrigermane, and cyclotristannane, (2) molecules containing EE double bonds including disilene, digermene and distannene, and (3) strained polycyclo[1.1.

Fundamentals of Silicon Chemistry: Molecular States of Silicon‐Containing Compounds

Hans Bock
- 01 Dec 1989 - 
TL;DR: In this paper, a set of clear and practical rules for interpreting measurements and planning experiments is presented for interpreting spectroscopic fingerprints of organosilicon compounds, which can be used to predict the connectivity between and the spatial arrangement of silicon building blocks, the energy-dependent electron distribution over the effective nuclear potentials of a molecular framework, and the partly considerable effects of "silicon substituents" on molecular properties.
