The reaction of P4 with [CoCp“(μ-CO)]2 in the presence of [Cr(CO)5THF] leads to [CoCp”(η4-P4){Cr(CO)5}3] (Cp“ = η5-C5H3 tBu2-1,3) (IUPAC formula [CoCp”[{Cr(CO)5}3(PH-1κP1,2κP2, 3κP3)] (κ-P1,P2,P3,P4)]) as a final product. An X-ray structural study reveals a complex with a planar cyclo-P4 ligand capped by a Cp”Co unit. Three of the phosphorus atoms are also coordinated to [Cr(CO)5] groups.
