Carbonyl complexes of transition metals with stabilized germylenes

The germylenes based on substituted diethylenetriamine and dialcohols were used as ligands for synthesis of new mono- and disubstituted (cis-/trans-) germanium(II) molybdenum and tungsten carbonyl complexes. The germylenes based on dialkanolamines and pyridine-containing dialcohols (O-ligands) gives cis-digermanium complexes. On contrary, germylenes based on diethylenetriamines (N-ligands) give trans-digermanium complexes.
