Abstract
A gold complex prepared through allowing a gold hydroxide salt to react with a hydantoin-based compound in an aqueous solution at a temperature between 30° C. to 80° C. in order to coordinate the hydantoin-based compound to gold ions. It is preferable that the reaction ratio of the gold hydroxide salt to the hydantoin-based compound is 1:2 to 1:4 in mole ratio.
