bistrimethylsilylamide, bis(trimethylsilyl)methyllithium and methyllithium yields the cyclopentadienyl containing germylene complexes Me5C5(R)Ge→W(CO)5 (5: R = (Me3Si)2N; 6: R = (Me3Si)2CH; 7: R = Me) as extremely air-sensitive orange crystals. An X-ray crystal structural investigation of 6 reveal the same dihapto bonding of the cyclopentadienyl ring as was found for 4, suggesting that the electron deficiency at the
