[PrCl(μ-Cl)2(tetrahydrofuran)2]n is a coordination polymer consisting of praseodymium (Pr) atoms, chloride (Cl) ions, and tetrahydrofuran (THF) molecules. In this complex, praseodymium serves as the central metal ion, while chloride ions act as bridging ligands, connecting adjacent praseodymium centers through μ-Cl bonds. The tetrahydrofuran molecules are terminal ligands, coordinating to the praseodymium ions in a bidentate fashion. The overall structure forms a one-dimensional polymeric chain, with the repeating unit being [PrCl(μ-Cl)2(tetrahydrofuran)2]. [PrCl(μ-Cl)2(tetrahydrofuran)2]n is of interest in the field of coordination chemistry, as it showcases the versatility of metal-ligand interactions and the formation of extended structures.
The CAS Registry Mumber 3639-27-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,3 and 9 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 3639-27: (6*3)+(5*6)+(4*3)+(3*9)+(2*2)+(1*7)=98 98 % 10 = 8 So 3639-27-8 is a valid CAS Registry Number.
