✦ Synopsis

Phosphorus / Chromium / Molybdenum / Cyclopentadienes / Sandwich complexes The reaction of [CpCr(CO) 3 ] 2 with P 4 in toluene at 90 °C for 5 h affords the triple-decker sandwich complex [CpCr(CO)(η 3 -P 3 )(CpCr) 2 (µ,η 1 :η 5 :η 5 -P 5 )] (1) as a new product, along with the previously described products with P 2 , P 3 , and P 10 units. The structure of the paramagnetic complex 1 has been established by single-crystal X-ray diffraction methods. A novel complex [{CpCr(CO) 2 } 2 (µ,η 1 :η 1 :η 2 -P 2 ){Mo(CO) 4 } 2 {(µ,η 1 :η 1 :η 5 :η 5 -P 5 )(CpCr) 2 }] (2) has been ob-
