title: [13,27-Dichloro-3,6,9,17,20,23-hexa-azatetracyclo-[23.3.1.1.0]triaconta-1(29),9,11,13,15(30),16,23,25,27-nona-ene-29,30-diol-κN,N,N,O,O]bis-(nitrato-κO,O')europium(III) nitrate methanol hemisolvate.
abstract: The title compound, [Eu(III)(NO(3))(2)(C(24)H(28)Cl(2)N(6)O(2))]NO(3)·0.5CH(3)OH, is isostructural with the Gd(III) and Ho(III) complexes of the analogous macrocyclic ligand, with both Cl atoms replaced by methyl groups. The Eu atom exhibits a nine-coordinate distorted tricapped trigonal-prismatic coordination geometry. The methanol solvent mol-ecule is disordered about a twofold rotation axis with occupancies of 0.543 (12):0.457 (12).
