The first complex to contain the N 2 O analogue P 2 O as a ligand is the tetranuclear cluster [{Cp*Fe}{Cp″Co} 3 (P 2 O)(PO)(P 2 )] ( 1 ), which is formed by the oxidation in air of [{Cp*Fe}{Cp″Co} 2 (P 4 )(P)] (Cp*=C 5 Me 5 ; Cp″=1,3‐ t Bu 2 C 5 H 3 ). The bent P 2 O ligand is doubly side‐on as well as terminally coordinated (σ,σ,π,π) to the four metal atoms (see picture). In addition, 1 contains a PO and a P 2 ligand.
