Herein, the synthesis of new low‐valent Group 14 phosphinidenide complexes [({SIDipp}P) 2 M ] exhibiting P–M pπ–pπ interactions (SIDipp=1,3‐bis(2,6‐diisopropylphenyl)‐imidazolidin‐2‐ylidene, M=Ge, Sn, Pb), is presented. These compounds were investigated by means of structural, spectroscopic, and quantum‐chemical methods. Furthermore, the monosubstituted compounds [(SIDippP)MX] 2 (M=Sn, X=Cl; M=Pb, X=Br) are presented, which show dimeric structures instead of multiple bonding interaction.
