P(2)O, the Phosphorus Analogue of N(2)O, as a Ligand in a Tetranuclear Cluster.
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-tBu(2)C(5)H(3)). The bent P(2)O ligand is doubly side-on as well as terminally coordinated (sigma,sigma,pi,pi) to the four metal atoms (see picture). In addition, 1 contains a PO and a P(2) ligand.
