"μ-(1,1,2,3,4,5,5-heptaphenylpentaphosphine-P(2),P(4))-bis[tetracarbonyliron(0)]" is a complex organophosphorus compound that features a central heptaphenylpentaphosphine ligand, which is a phosphorus-containing molecule with seven phenyl groups attached. This ligand is coordinated to two iron(0) centers, each of which is in the form of a tetracarbonyl complex, meaning each iron atom is surrounded by four carbon monoxide molecules. The compound is characterized by its unique structure, where the phosphorus atoms at positions 2 and 4 are involved in bridging the two iron centers. This type of compound is of interest in the field of organometallic chemistry, particularly for its potential applications in catalysis and the study of metal-phosphorus interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 74005-06-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,0 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74005-06:
(7*7)+(6*4)+(5*0)+(4*0)+(3*5)+(2*0)+(1*6)=94
94 % 10 = 4
So 74005-06-4 is a valid CAS Registry Number.

Reactions of Coordinated Ligands, VII. Syntheses and Reactions of Transition Metal Carbonyl Complexes of PH-Functional Di-, Tri-, and Tetraphosphanes

, p. 1328 - 1342 (2007/10/02)

The synthesis of complexes of PH-functional diphosphanes (CO)mM(PhPH - PR2)n (M = Mo, m = 4, 5, n = 2, 1, R = Ph, tBu; M = Fe, m = 4, n = 1, R = Ph) (7 - 10) and of 1,2,3-triphenyltriphosphane (CO)mM - PPhH - PPh - PPhH - M(CO)m (M = Mo, Fe, m = 5, 4) (13, 14) is reported.The availability of PH-functional groups as well as uncoordinated P-atoms in these compounds permits the formation of new P - P-bonds and of heterometallic complexes such as (CO)5Mo(PhPH - PPh2)Ni(CO)3 (16) or (CO)5Mo - PPhH - PPhPPhH - Mo(CO)5 (17).The 1H- and 31P NMR spectra of the complexes 4 - 10 and 13 - 20 are discussed.For complexes of 1,1,2,3,3-pentaphenyltriphosphane, (Ph2P)2PPH - M(CO)m (M = Mo, Fe, m = 5, 4) the migration of the (CO)mM group from the medial to the terminal position of the P3-skeleton could be observed by means of 31P NMR spectroscopy.
