ZnBr2(N,N,N',N'-tetramethylethylenediamine) is a coordination compound consisting of zinc bromide (ZnBr2) and N,N,N',N'-tetramethylethylenediamine (TMEDA) as a ligand. In this complex, zinc (Zn) is the central metal ion, and it is coordinated to two bromide ions (Br-) and two TMEDA molecules. TMEDA is a bidentate ligand, meaning it can bind to the metal ion through two donor atoms, in this case, the nitrogen atoms. The overall charge of the complex is neutral, and it is often used as a catalyst or a precursor in various chemical reactions. The presence of the TMEDA ligand can influence the reactivity and selectivity of the complex, making it a valuable tool in synthetic chemistry.
The CAS Registry Mumber 28307-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,0 and 7 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 28307-98: (7*2)+(6*8)+(5*3)+(4*0)+(3*7)+(2*9)+(1*8)=124 124 % 10 = 4 So 28307-98-4 is a valid CAS Registry Number.
