Abstract
The atomic structure of europium acrylate crystals [Eu2(Acr)5OH·3H2O]·2(0.5H2O) was studied by X-ray analysis (a = 24.360(3) Å, b = 18.466(2) Å, c = 8.5818(9) Å, β = 96.087(2)°, space group C2/c, Z = 6, ρcalc = 2.036 g/cm3). The crystal structure involves chains of binuclear [Eu2(C3H3O2)5OH·3H2O] molecules, running infinitely in the [101] direction and having pairs of C9H9EuO7H2O molecules alternating with C6H6EuO4OH·2H2O molecules that link the pairs. The infinite chains are linked by hydrogen bonds and van der Waals interactions. The thermal behavior of luminescence of the europium(III) complex is discussed.
