Beschreibungen/Notizen

• A new series of germanium (1–5) and tin (6–10) complexes were successfully synthesized by employing N‐alkoxy‐functionalized carboxamides as stabilizing ligands, and these complexes could potentially serve as precursors for thin‐film applications. All of the complexes were characterized by FTIR and NMR spectroscopy as well as elemental and thermogravimetric (TG) analyses. The single‐crystal X‐ray diffraction studies of 5 and 10 revealed that they crystalize in the monoclinic space group P2(1)/c as monomers. The metal centers in these complexes are coordinated to four oxygen atoms and display distorted trigonal‐bipyramidal geometries. The thermogravimetric analysis and volatility studies of the complexes demonstrated the good volatilities and stabilities of 2–4 and 6–9. Among these complexes, Ge(mdpa)2 (3, mdpaH = N‐methoxy‐2,2‐dimethylpropanamide) and Sn(edpa)2 (9, edpaH = N‐ethoxy‐2,2‐dimethylpropanamide) exhibited excellent physicochemical properties with clean single‐step curves and low residual masses in their TG analyses. Alkoxy‐functionalized carboxamides act as excellent stabilizing ligands for germanium and tin complexes, and the physicochemical properties of these complexes prove their potential as precursors for thin‐film deposition.
