2-Propenoic acid, 3-phenyl- → Europium(3+);tris(3-phenylprop-2-enoate)

Participants

Reaction Steps

Then a sodium cinnamate aqueous solution obtained in advance by dissolving 1.64 g of sodium hydroxide in 300 ml of purified water and thereafter dissolving 6.06 g of cinnamic acid (purity 99.9%, conjugate number 4) thoroughly in the resultant solution was gradually added with continued stirring into the aforementioned aqueous europium chloride solution. Consequently, a white salt of europium cinnamate was produced in the form of a precipitate. Thereafter, the reaction solution was adjusted to pH 6.5 with a 0.1 N sodium hydroxide aqueous solution added under thorough stirring.
