The title compound (13,27-dimethyl-3,6,9,17,20,23-hexaazatricyclo-[23.3.1.111,15]-triaconta-1(29),2,9,11,13,15(30),16,23,25,27- decaene-29,30-diol-N3, N6, N9, O29, O30)-bis (nitrato-O,O’)-europium (III) nitrate hydrate ([EuL(NO3)2](NO3)·H2O, L denotes the macrocyc-lic ligand) was prepared and characterized by elemental analysis, infrared spectra, and electrospray mass spectra. Its crystal and molecular structure was determined by X-ray diffraction. The crystal crystallized in the monoclinic system, space group C2/c with a=2.3757 (4) nm, b=1.4302(3) nm, c=1.9584(3) nm, β=91.654(5)°, M=818.60, V=6.651(2) nm3, Z=8, D=1.635 g/cm, F(000)=3312, R=0.0542, wR=0.1045. The central ion Eu3+ was nine-coordinated in the coordinaton geometry of a distorted tricapped trigonal prism. The macrocycle was coordi-nated through two oxygen and three nitrogen atoms. Two nitrate are chelate in the opposite positions of the macrocycle, the third nitrate be-ing ionic. At room temperature, excitation of the title complex gave rise to the characteristic emissions of the Eu3+ ion.
