Figure 12.

Calculated minimum structure of [Cu(NCMe)(Ge2P2{CpFe(CO)2}2)]−, and a cutout of the contour plot of the HOMO as the relevant bonding orbital (Ge: sky blue, P: light green, Cu: pink, Fe: dark yellow, O: red, N: blue, C: black, H atoms are omitted for clarity; contour values: ±0.05 a. u.).
