摘要
The complexation of mercury(II) cyanide with macrocyclic ligands 15-crown-5,18-crown-6 and dibenzo-24-crown-8 in dimethylsulfoxide was studied using199Hg NMR measurements. No significant complexation with 15-crown-5was observed. The stability constants Ks for 1 : 1 complexes with two other ligands were determined and found to be similar, in contrary to the results reported in nitrobenzene. Solvent effects on Ks values obtained are discussed in comparison with the literature data. X-ray crystal structure of Hg(CN)2.A18-crown-6 was also determined.
