The dinuclear palladium(I) complexes [L-(Ar2HGe)Pd(μ-GeAr2)2Pd(GeHAr2)L] (Ar = Ph, p-Tol; L= PMe3, tBuNC) contain terminal germyl and bridging germylene ligands with the experimentally observed Ge...Ge bond lengths of 2.8263(4) ? (L = PMe3) and 2.928(1) ? (L = tBuNC), which are close to the longest Ge-Ge bond reported to date [2.714(1) ?]. Significant Ge...Ge interactions between the germylene and germyl ligands (PMe3 complexes > tBuNC complexes) are supported by DFT calculations, Wiberg bond indices (WBI), and natural bond orbital (NBO) analyses. Exchanging tBuNC for PMe3 ligands increases the Ge...Ge interaction, and simultaneously activates two Pd-Ge bonds. Adding the chelating diphosphine 1,2-bis(diethylphosphino)-ethane (depe) to the PMe3 complexes results in the intramolecular coupling of germyl and germylene ligands followed by extrusion of a digermane.

The reactions of diarylgermanes with alkali metals in HMPA/THF or THF were found to give the corresponding diarylgermylenedialkali metals in high yields.Diphenylgermylenedipotassium reacted with aryl halides or carbonyl compounds to give reduction products predominantly.With alkyl halides, diphenylgermylenedipotassium gave mainly substitution products.
