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） nm^3, Z=8, D=1.635 g/cm, F（000）=3312, R=0.0542, wR=0.1045. The central ion Eu^3＋ was nine-coordinated in the coordinaton geometry of a distorted tricapped trigonal prism. The macrocycle was coordinated through two oxygen and three nitrogen atoms. Two nitrate are chelate in the opposite positions of the macrocycle, the third nitrate being ionic. At room temperature, excitation of the title complex gave rise to the characteristic emissions of the Eu^3＋ ion.

| Abstract: | 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 macrocyclic 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 coordinated through two oxygen and three nitrogen atoms. Two nitrate are chelate in the opposite positions of the macrocycle, the third nitrate being ionic. At room temperature, excitation of the title complex gave rise to the characteristic emissions of the Eu3+ ion. |
