Abstract The title complex was prepared by the addition of 15-crown-5, dissolved in acetone, to a solution of Y(NO3)3·nH2O in the same solvent. The crystal structure of this complex, determined by single-crystal X-ray diffraction using counter methods, was carried out on a crystal grown by slow evaporation of the reaction mixture at room temperature. [Y(NO3)3(OH2)3]·1.5(15-crown-5) Me2CO crystallizes in the acentric space group, P21, with unit cell dataa=15.900(5),b=16.530(6),c=11.821(5) Å,β=92.12(3)°,D calc=1.53 g cm−3 forZ=4. Each unit cell consists of two dimers of the formula unit. One crown molecule bridges two [Y(NO3)3(OH2)3] units via hydrogen bonding with one water molecule of each. The two remaining water molecules per metal moiety form three hydrogen bonds to another 15-crown-5 molecule and one to an acetone molecule. The average bonding parameters in the nine-coordinate metal complexes are Y-O(NO3)=2.43(4) Å and Y-O(OH2)=2.34(5) Å.
