The ligand properties of a series of aryl oligogermanes R 3 Ge‐GeAr 3 , 3 – 7 [Me 3 Ge‐GePh 3 ( 3 ), Me 3 Ge‐Ge( p Tol) 3 ( 4 ), Ph 3 Ge‐GePh 3 ( 5 ), (C 6 F 5 ) 3 Ge‐GePh 3 ( 6 ), Ph 3 Ge‐GeMe 2 GePh 3 ( 7 )] for the synthesis of transition metal carbonyl complexes such as R 3 Ge‐GeAr 2 (R′C 6 H 4 ‐η 6 )M(CO) 3 (M = Cr, 3a – 7a ; M = Mo, 3b ; M = W, 3c ) were investigated. The target complexes were obtained in moderate yields using several different synthetic approaches. The physicochemical properties of these new derivatives were investigated by IR, UV/Vis, NMR spectroscopy, electrochemistry, and DFT calculations. The molecular structures of 3c , 4a , and 5a were studied by single‐crystal X‐ray diffraction analysis. A comparative analysis of donor and acceptor properties of aryl oligogermanes as ligands for transition metal carbonyl complexes is reported.
