The title compound (13, 27-dichloro-3, 6, 9, 17, 20, 23-hexaazatricyclo-[23.3.1.1(11,15)]-triaconta-1(29), 2, 9, 11, 13, 15(30), 16, 23, 25, 27-decaene-29, 30-diol-N(3), N(6), N(9), O(29), O(30))-bis(nitrato-O,O)-Europium(III) nitrate was prepared and characterized by elemental analysis, infrared spectra, electrospray mass spectrum and X-ray diffraction, respectively. The crystal of the complex crystallizes in the monoclinic system, space group C2/c with a = 2.3737(2) nm, b = 14.333(1) nm, c = 19.388(2) nm, beta = 91.804(1)degrees, M(r) = 850.4, V = 6.5929(8) nm(3), R = 0.0333, wR = 0.0936. At room temperature, excitation of the title complex gives rise to the characteristic luminescent emissions of the Eu(3+) ion.
