Tris(4,4'-dimethylbipyridine)chromium(II) ion, also known as [Cr(4,4'-dimethyl-2,2'-bipyridine)3]2+, is a coordination complex consisting of a central chromium(II) ion (Cr2+) coordinated to three 4,4'-dimethylbipyridine ligands. tris(4,4'-dimethylbipyridine)chromium(II) ion is a well-known example of a metal-ligand complex, where the chromium ion is surrounded by the three bidentate ligands, forming an octahedral geometry. The 4,4'-dimethylbipyridine ligands are derivatives of bipyridine, with methyl groups attached to the 4 and 4' positions, which can influence the electronic properties and stability of the complex. This particular complex is of interest in various fields, including coordination chemistry, as it demonstrates the ability of metal ions to form stable complexes with organic ligands, and it has been studied for its potential applications in areas such as catalysis and luminescent materials.
The CAS Registry Mumber 47837-99-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,7,8,3 and 7 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 47837-99: (7*4)+(6*7)+(5*8)+(4*3)+(3*7)+(2*9)+(1*9)=170 170 % 10 = 0 So 47837-99-0 is a valid CAS Registry Number.
