Reaction of 2 equiv of the previously reported germolyl anion Li[C4Me4GeSi(SiMe3)3] withFeCl2(THT)1.5 (THT = tetrahydrothiophene) at low temperature gave the new bis-
5-germolylcomplex [5-C4Me4GeSi(SiMe3)3]2Fe (1), which was characterized by X-ray crystallography.Reaction of 1 with I2 resulted in loss of the germolyl ligand as C4Me4Ge(I)[Si(SiMe3)3], whilethe reaction with MeLi produced the ferrocenophane ansa-(Me3Si)2Si(5-GeC4Me4)2Fe (4).X-ray crystallographic analysis of this compound revealed that the Ge atoms are displacedsignificantly out of the C4 plane. Attempts to induce the ring-opening polymerization of 4were unsuccessful.
