Abstract: | The complex {[Eu2F34H2O]3H2O}n (H2F = fumaric acid) has been synthesized and structurally characterized by single crystal X-ray diffration methods. The complex crystallizes in the monoclinic system with space group P21/n, lattice parameters a = 9.475(3) Å, b = 14.700(5) Å, c = 14.810(4) Å, = 90, = 91.250(5), = 90, V = 2062.1(11) Å3, Z = 4, Dcalc = 2.487 Mg/m3. The Eu(III) center is in distorted tricapped trigonal prism coordination environment that is coordinated by nine oxygen atoms, seven from five F2– groups, two from two water molecules. Eu(III) ions are connected into three-dimensional coordination network structure by the oxygen atoms of the carboxyl groups and hydrogen bonds. |
