160954-34-7

[Os3(CO)10(P5(C6H5)5)] is a triosmium carbonyl cluster featuring an intact pentaphenylcyclopentaphosphine (P5Ph5) ligand coordinated to the Os3 core. It is formed through the reaction of P5Ph5 with activated triosmium precursors such as [Os3(CO)10(NCMe)2], resulting in isomers where the cyclopolyphosphine ring remains structurally preserved. The cluster exemplifies the ability of polyphosphine ligands to bind to transition metal frameworks while retaining their cyclic geometry, as confirmed by X-ray crystallography. Other names for [Os3(CO)10(P5(C6H5)5)] may include its isomeric forms or derivatives, but no specific alternative nomenclature is provided in the given abstracts.

Check Digit Verification of cas no

The CAS Registry Mumber 160954-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,9,5 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 160954-34:
(8*1)+(7*6)+(6*0)+(5*9)+(4*5)+(3*4)+(2*3)+(1*4)=137
137 % 10 = 7
So 160954-34-7 is a valid CAS Registry Number.

Structural and nuclear magnetic resonance studies of triosmium and triruthenium carbonyl cluster derivatives containing pentaphenylcyclopentaphosphane

Ang, How-Ghee,Ang, Siau-Gek,Zhang, Qi

, p. 3843 - 3851 (2007/10/03)

The reaction of pentaphenylcyclopentaphosphane (PPh)5 with [Os3(CO)10(NCMe)2] in 1:1 molar ratio afforded a pair of inversion isomers, 1 and 2, with the molecular formula [Os3(Cp)10{(PPh)5}]. A similar reaction in 3:1 molar ratio gave a different cluster [Os3(CO)10{(PPh)5}2] 3. The clusters [Os3(CO)11{(PPh)5}] 4 and [{Os3(CO)11}2{(PPh)5}] 5 were obtained from reaction of (PPh)5 with [Os3(CO)11(NCMe)]. Compound 4 reacted with [Ru3(CO)11(NCMe)] to generate the cluster [(OC)11Os3{(PPh)5}Ru3(CO) 11] 6. Compounds 4 and 5 were converted into 1 and 2 when heated in sealed tubes at 80°C. In clusters 1 and 2 the triosmium unit is chelated by the cyclophosphane ligand through the 1,3-phosphorus atoms of the ring, and their main difference lies in the orientations adopted by the aromatic rings attached to the unco-ordinated phosphorus. Variable-temperature NMR studies showed that the two inversion isomers can undergo interconversion. In 4 one osmium atom of the triosmium unit is co-ordinated to one phosphorus atom of the cyclophosphorus ligand, while in 5 the two triosmium units are each linked via co-ordination of one Os atom to a phosphorus atom of the cyclophosphane ring. With the help of two-dimensional 31P NMR spectroscopy, the correlations between phosphorus atoms for clusters 1, 2, 4 and 5 were established.
