The given chemical formula represents a coordination complex, ZnCl((C6H5NCCH3)2NC5H3)(NO3), which consists of a central zinc ion (Zn2+), a chloride ion (Cl-), a nitrate ion (NO3-), and a bidentate ligand ((C6H5NCCH3)2NC5H3). The bidentate ligand is a derivative of pyridine, with two phenyl groups (C6H5) attached to the nitrogen atom, and a methyl group (CH3) attached to the adjacent carbon atom. The complex has a tetrahedral geometry around the central zinc ion, with the chloride ion and the two nitrogen atoms of the bidentate ligand occupying three of the coordination sites, and the nitrate ion occupying the fourth site. This complex is an example of a metal-organic framework, where the metal ion is coordinated to an organic ligand, and it can exhibit various properties depending on the specific ligands and metal ions involved.
The CAS Registry Mumber 82025-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,2 and 5 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 82025-57: (7*8)+(6*2)+(5*0)+(4*2)+(3*5)+(2*5)+(1*7)=108 108 % 10 = 8 So 82025-57-8 is a valid CAS Registry Number.
