<P><B>Abstract</B><P>LGa(P2OC)cAAC2features a 1,2‐diphospha‐1,3‐butadiene unit with a delocalized π‐type HOMO and a π*‐type LUMO according to DFT calculations. [LGa(P2OC)cAAC][K(DB‐18‐c‐6)]3[K(DB‐18‐c‐6] containing the 1,2‐diphospha‐1,3‐butadiene radical anion3⋅<SUP>−</SUP>was isolated from the reaction of2with KC8and dibenzo‐18‐crown‐6.3reacted with [Fc][B(C6F5)4] (Fc=ferrocenium) to2and with TEMPO to [L<SUP>−H</SUP>Ga(P2OC)cAAC][K(DB‐18‐c‐6)]4[K(DB‐18‐c‐6] containing the 1,2‐diphospha‐1,3‐butadiene anion4<SUP>−</SUP>. The solid state structures of2,3K(DB‐18‐c‐6], and4[K(DB‐18‐c‐6] were determined by single crystal X‐ray diffraction (sc‐XRD).</P></P>
