Bis(indenyl)tetrelocenophanes: Introducing ansa-Indenyl Ligand Systems to the p‑Block

The synthesis and characterization of bis(indenyl)tetrelocenophanes of germanium(II), tin(II), and lead(II) are reported, which are examples of bis(indenyl)metallocenophane-type species of p-block elements. The structural characterization of these species in the solid state revealed some unusual features, including a dispersion dimer and an arene complex.
