摘要：

Exclusively nitrogen atoms constitute the co‐ordination sphere of germanium in 1. The NGe donor bond fluctuates, as observed for the analogous GeS compound 2. In the analogous iron complex 3, on the other hand, it is static on the NMR time scale, at least up to 90°C. Whereas a GeFe single bond is present in 3, partial GeN double‐bond character is found for 1. Furthermore, a zwitter‐ionic resonance structure must be considered in describing 1.
