Synthesis of Cyclotetragermanes of the Type of [R(Ph)Ge]4 and Conversion to [R(Cl)Ge]4. The First Functionalized Cyclotetragermanes
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.read more

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.

Synthesis and characterization of tetrakis(2,6‐diethylphenyl)digermene
TL;DR: Tetrakis(2,6-diethylphenyl)digermene (1b) has been synthesized and its molecular structure determined: (1) the GeGe bond length is 2.213(2) A and (2) the molecule has a twist angle of 11° about the Ge-Ge bond and an out-of-plane bending angle of 15° at the germanium atoms as discussed by the authors.

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