Abstract

A naphthyridine diimine (NDI) supported bis(germylene) NDI-Ge₂ containing two dicoordinate, coplanar Ge(II) atoms has been synthesised. Computational investigations on NDI-Ge₂ indicated the two Ge(II) atoms are nearly independent. The EDA-NOCV analysis of the [NDI-Ge₂][Fe₂(CO)₆] complex revealed the six-electron donor behavior of NDI-Ge₂, the first example for group-14-element-based bidentate ligands.
