Abstract
The crystal and molecular structure of the compound [Dy(NO3)3(H2O)3]L (L = (2-methoxy-1,3- xylyl)-15-crown-4) was determined from three- dimensional X-ray diffraction analysis. The crystals are triclinic, space group P1; the unit cell has a = 12.312(5), b = 10.193(4), c = 10.264(4) Å, α = 95.1(3), β = 94.5(3), γ = 92.5(3), and Z= 2. The structure was refined by least-squares techniques to R = 4.2% for 3829 independent reflections. The coordination polyhedron around the Dy atom is a quasi-ideal tricapped trigonal prism formed by six oxygen atoms of the bidentate nitrate groups and by three oxygen atoms of the coordinated water molecules. The crown ether L is linked to the [Dy(NO3)3(H2O)] moiety through hydrogen bonds which favour also the formation of an extensive three- dimensional H-bonding network. © 1985.
