Formation of Ge-Ge and Ge-Si bonds has been achieved by electroreduction with an Mg electrode and this method has been successfully applied to the preparation of polygermane and germane-silane copolymer.

The synthesis and structure of the unknown trimethylgermyltriphenylsilane (I, Ph3SiGeMe3) is reported.The molecular geometry is compared to that of the isomeric Me3SiGePh3 (II) and the related Ph3SiSiMe3 (III) and (η5-C5H5)Fe(CO)2SiMe2GePh3 (IV).The Si-Ge bond of I is significantly longer than that for II.We suggest that this is due to expansion of Ge bonding orbitals by the relatively electron-donating methyl groups in conjunction with the contraction of the corresponding orbitals of Si due to the electron-withdrawing phenyl groups.The overall result is a better orbital overlap between the Si and Ge atoms for II.
