英文摘要density functional theory (dft) was utilized to simulate the reactions occurred in the mixture solution of cysteine and hg(ii) ions with the ratio < 2. simulation result shows that hg ions will coordinate to cysteine by the thiol groups with the form of s-hg-2 and s-hg-3, and moreover, the content of free hg ions can only be reduced by these two forms. oh- plays an important role in the growth of beta-hgs, because its nucleophilic substitution reaction supplies plenty of hg-s-hg radicals, which will be adsorbed onto the surface of liquid mercury ball and form the precursor of beta-hgs(111) plane. three valent bonds adsorption of hg-s-hg radicals onto the surface of hg ball has more adsorption energy (-32.768 kcal mol(-1)) than that of two valent bond adsorption (-20.882 kcal mol(-1)). hg balls will stop growing after completely covered with hg-s-hg radicals and their size will be limited. the growth direction of beta-hgs is parallel to the "repelling" force, that is [111] direction in beta-hgs lattice. the calculated results are in good agreement with the experimental observations, demonstrating that the dft method can be taken as a very useful tool to interpret the solution reactions that cannot be solved by conventional methods.
