The chemical compound "[Rh2Cl(CO)2(1,1-bis(diphenylphosphino)ethane)2][RhCl2(CO)2]" is a rhodium-based complex with a unique structure. It consists of two rhodium atoms, each coordinated with a chloride ion, a carbonyl group (CO), and a 1,1-bis(diphenylphosphino)ethane ligand, which is a bidentate phosphine ligand. The compound also includes an additional rhodium atom coordinated with two chloride ions and two carbonyl groups. This complex is known for its catalytic properties, particularly in the field of homogeneous catalysis, where it can facilitate various chemical reactions due to its ability to activate small molecules like hydrogen and carbon monoxide. The presence of the phosphine ligand plays a crucial role in stabilizing the rhodium center and modulating its electronic properties, which in turn affects the reactivity and selectivity of the catalyst.
The CAS Registry Mumber 79980-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,8 and 0 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 79980-45: (7*7)+(6*9)+(5*9)+(4*8)+(3*0)+(2*4)+(1*5)=193 193 % 10 = 3 So 79980-45-3 is a valid CAS Registry Number.
