Ge[N(SiMe 2 i Pr) 2 ] 2 : Ein neues Germylen und dessen Koordinationschemie führt zu der kürzesten Ge–Co‐Bindung

Ge[N(SiMe 2 iPr) 2 ] 2 : A New Germylene and its Coordination Chemistry leads to the Shortest Ge–Co Bond The high temperature reaction of Germanium with HBr, which is used for the synthesis of GeBr leads at a higher reaction pressure to a mixture of GeBr and GeBr 2 . GeBr 2 reacts with the lithiumsalt LiN(SiMe 2 i Pr) 2 in good yield to the germylene Ge[N(SiMe 2 i Pr) 2 ] 2 . Subsequent reaction of this germylene with Co 2 (CO) 8 leads to the germanium cobalt cluster compound {Co(CO) 3 Ge[N(SiMe 2 i Pr) 2 ] 2 } 2 featuring the shortest Ge–Co bond giving hints to a possibly multiple bonded system.
