"WI(η3-allyl)(CO)2(Ph2AsCH2CH2AsPh2)" is a complex organometallic compound, featuring a tungsten (W) center. The compound is characterized by a η3-allyl ligand, which means the allyl group is bonded to the metal through three atoms, creating a cyclic structure. It also contains two carbonyl (CO) ligands, which are common in organometallic chemistry and serve as electron-pair donors. The compound is further stabilized by a bidentate ligand, Ph2AsCH2CH2AsPh2, which consists of two phenylarsine groups connected by a two-carbon chain. This ligand provides additional stability through its chelating effect. Overall, the compound is an example of a transition metal complex with a unique set of ligands, which may have potential applications in catalysis or as a precursor in the synthesis of other organometallic compounds.
The CAS Registry Mumber 75213-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,1 and 3 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 75213-57: (7*7)+(6*5)+(5*2)+(4*1)+(3*3)+(2*5)+(1*7)=119 119 % 10 = 9 So 75213-57-9 is a valid CAS Registry Number.
